摘要： PURPOSE:To form a small-sized antenna by providing a switch connected between different two points on the way of a remaining loop conductor except a part connected with a varactor element and capable of short-circuiting the two points selectively and providing a T matching circuit conductor to the loop conductor so as to use one end of the T matching circuit conductor as a feeding terminal. CONSTITUTION: In closing switches 3a, 3b, the loop area is decreased effectively, the inductance is reduced and the same varactor element is used to, tune a high frequency band. In case of the switches 3a, 3b opened, the loop area is increased and the inductance is increased and the antenna is tuned to a low frequency band. Thus, the signals of plural lower frequency bands are extracted from one feeding point by using one varactor element. Moreover, a signal of a higher frequency band is extracted from an output terminal of the T matching circuit conductors 10a, 10b provided to the loop conductor.

摘要： PURPOSE:To remove snow adhered to a reflection mirror by allowing the effect of a spring mounted to a connecting part between a soft rubber and an arm, the arm itself and the unidirectional flexibility of the soft rubber to make the soft rubber contact the reflection mirror face and driving the soft rubber by a motor. CONSTITUTION:In receiving a satellite broadcast by an offset parabolic antenna, when snow is adhered to the reflection mirror 1, a drive motor 5 is driven to drive the arm 4 and the soft rubber 3 connected to the arm 4 is driven. The depth of the mirror face of the mirror 1 changes depends on the position of the driven rubber, but the mirror face of the mirror 1 and the soft rubber 3 are kept contacted even when the rubber 3 is driven by the operation of the spring 9 mounted to the connecting part between the arm 4 and the soft rubber 3 and of the soft rubber 3 to which a spring plate 8 is inserted. That is, the rubber 3 is shaken to the right left on the mirror face while the rubber 3 is kept contact onto the mirror face of the reflection mirror 1 and the snow adhered to the mirror face is removed by the soft rubber 3.

摘要： PURPOSE:To lighten the weight of a plane antenna itself, and at the same time, to reduce a line loss by using a plate-shaped body with a polygon structure. CONSTITUTION:Since it is constituted by a sandwich structure by adhering a first substrate 1, in which slots S1-S3 are formed on the plate-shaped body, and a second substrate 5, provided with a copper foils 3, 4 on the surface of all one sides, an electro magnetic wave, emitted from micro strip lines l1-l3, are reflected by a copper foil surface and emitted through the slots S1-S3. Then, since the circumference of this sandwich structure is surrounded by a conductive frame 20, the electro magnetic wave, emitted from the micro strip lines l1-l3, is not directly emitted toward a free space as an emission loss. Thus, the line loss is reduced, and the electro magnetic wave is emitted from the slot at a high efficiency. Besides, since the plate-shaped body to form the plane antenna is made into a polygon structure, the weight can be lightened and a strength can be improved.

摘要： PURPOSE:To reduce a running wind pressure, and also to solve a problem such as a car height limit in case when an automobile is garaged, etc. by installing a reflector having an offset parabolic surface to a roof of a car body so as to become roughly horizontal, when the automobile is running. CONSTITUTION:A primary radiator 6 is installed to an offset type reflector 7 through an arm 11, and the reflector 7 is installed to an elevation azimuth variable device 8. In Japan, a direction for receiving a radio wave is an elevation, 30-60 deg. is enough, and in case of an offset type reflector, it can be designed roughly horizontally on a roof of a car, when an elevation angle is 45 deg., and by setting an elevation variable range to 45 deg.+ or -15 deg., a satellite broadcast can be received in most of areas. Also, at the running time when a broadcast is not received, the reflector 7 can be set horizontally, therefore, a running wind pressure is reduced, and also a problem of a car height limit in case when an automobile is garaged can also be solved.

摘要： PURPOSE:To set easily an elevating angle and an azimuth angle on ground in the direction of a satellite in a short time by forming a shape of an aperture of a reflector so as to provide wide and narrow directivity to both horizontal and vertical faces and providing a direction adjustment device matching earlier the wide directivity. CONSTITUTION:The antenna consist of a reflector 4, a primary radiator 5, a fixed device 6 and an elevating angle detecting meter 7 and the reflector 4 is formed to a shape having a long width and a short depth. When the area of aperture is unchanged, the gain is kept nearly identical, the beam width of the vertical directivity is wider and the beam width of the horizontal directivity is narrower. First the reflector 4 is adjusted so as to allow the elevating angle of the detecting meter 7 to be directed in the designated direction, then the parabolic antenna is directed in the azimuth toward the satellite by using an azimuth magnetic pointer and the azimuth is adjusted so as to maximize a reception output. since the beam of the vertical directivity is wide, when the azimuth is adjusted by moving the horizontal plane to the right and left, the disabled reception of a radio wave from the satellite is avoided and it is easy to apply minute adjustment of the elevating angle and azimuth after the radio wave is caught once.

First, a reflection mirror 6 is adjusted by an elevating angle adjuster 9 to allow an elevating angle detection meter 11 to point out a designated elevating angle. Then an azimuth angle to a satellite is confirmed by using an azimuth magnetic needle, an azimuth angle adjuster 10 is used to direct the mirror 6 toward the satellite and the azimuth angle is adjusted to maximize the reception output. In varying the phase amount between the parabolic antenna 15 and a synthesizer 14, the beam of the horizontal directivity of the combined directivity is moved. The phase adjusting device 13 is changed by utilizing it to adjust minutely the azimuth angle to maximize the reception output.

摘要： PURPOSE:To attain broad band and to decrease the axial length by providing a window transmitting an electric field E1 and shutting an electric field E2 in a circular waveguide through which the fields E1 and E2 orthogonal to each other are transmitted, providing a probe transmitting/receiving the field E2 to the forward/backward position of the window respectively so as to transmit a radio wave in the TEM mode between both the probes. CONSTITUTION:The electric fields E1, E2 orthogonal to each other in the Z axis direction are propagated in the circular waveguide 20. The field E1 transmits a window 2 and is given to an output terminal 4. The electric field is referred to as E1'. Although the field E2 at the input terminal cannot transmit through the window 2 due to the cut-off wavelength of the window 2, the field E2 is received by the probe 6. The field E2 received by the probe 6 transmits through a line 5, goes to the probe 7 at the output side, from which the field is irradiated toward the output terminal 4. The field is transmitted through the line 5 in the TEM mode. The input electric field E2 becomes to an output electric field E2'. The phase of the output electric field E2' is delayed by 90 deg. from the phase of the field E1' by selecting the length of the line 5. Further, the position of the probes 6, 7 is selected to be matched with the characteristic impedance of the line 5.

CONSTITUTION:The antenna device consists of a helical element 30, the receptacle 50 and the reflecting plate 40. A terminal 31 at a feeding point of the element 30 is bent gently toward the helical center axis A-A', enters the outer conductor 51 of the receptacle 50 and becomes a center conductor 32. A hole 52 having a diameter less than the maximum diameter of the element 30 is drilled in the center of the outer conductor 51, and the hole 52 is linked to a hole 53 being a 50-ohm impedance via a section having a specific constant impedance. The holes 52, 53 are filled with ''Teflon,'' which supports the center conductor 32. The element 30 is supported in a free space, the axial symmetry of the directivity is improved, the cross polarized wave characteristic and the axis ratio are improved and stable and excellent circularly polarized wave characteristics are attained.
