摘要： PURPOSE:To enhance the precision to eliminate the work distortion and make the weight light, by using thin waveguide materials and by molding them by etching. CONSTITUTION:Mold 11 of the same rectangular section as inside dimensions of the waveguide adapted to a used frequency band is molded by a low-melting point alloy or a synthetic resin. Thin metallic film 12 of an aluminum alloy or copper is formed around mold 11 by the metallic plating technique. Mold 11 is removed from thin film 12 to form rectangular waveguide 12'. Then, a mask is used to perform the etching treatment of waveguide 12', thereby forming slots 13 on waveguide 12'. Since these slots are formed with a high precision by etching, the burr generated at the mechanical work time is prevented, and a high work precision is obtained.

摘要： PROBLEM TO BE SOLVED: To effectively use material and reduce a cost for treating industrial waste by forming an electric field type antenna at the frame part of a substrate in contact with a carrying roller to be used for a re-flow process for soldering circuit parts to a substrate. SOLUTION: An antenna part 12 is connected with a matching part between with a receiver by a conductor pattern. The radio-radiating characteristic of the part 12 is non-oriented. In addition, a frame part 14a or 14d except for the antenna part 12 of a substrate 11 can properly be cut off on condition when a selective radio call receiver is incorporated to the main body. Since the part 12 and a circuit part 13 are constituted on the same substrate in the substrate constitution of portable radio equipment based on this form, a producing process can be reduced to improve productivity. In addition, since a part of the frame part to be wasted is used as the antenna part in the circuit substrate adopting a re-flow process in this substrate constitution, the material is effectively used.

摘要： PURPOSE:To realize a broad band and ominidirectional stub multiple loading antenna. CONSTITUTION:Since a loss substance is loaded between stubs 4 by increasing an open angle of a V dipole 3 as 110-120 degrees and forming the antenna onto a dielectric board 2, the travelling wave is attenuated by a loss of the radiation of the stubs 4 as well as a loss by a loaded conductance, then the broad band and ominidirectional antenna is realized.

摘要： PURPOSE:To obtain an antenna device with an increased directivity and gain for observing the ionized layers by constituting >=2 triangle antennas where the base having a feeding point is shared in common. CONSTITUTION:In a travelling wave feeding antenna where a triangle is constituted by using conductors 1, 2, 3, 4 longer than the wavelength, its vertex is provided with a terminating load 5 and its base is provided with a feeding point 6, its bases 3, 4 are provided in parallel with a ground 7, a triangle antenna is constituted by sharing the bases 3, 4 in common with conductors 8, 9 longer than the wavelength and a terminating load 10. Each main beam from the conductors 1, 2, 8, 9 is matched to a normal taken above the ground 7 by selecting suitably the length of the conductors 1, 2, 8, 9, an angle to the ground 7, and phase adjusters 11, 12, allowing to increase the directivity and the gain.

摘要： PURPOSE:To secure the non-directivity within the horizontal plane and the sharp directivity within the vertical plane respectively with formation of a composite antenna by sticking together two MSL (microstrip line) antennas of the plane symmetry. CONSTITUTION:MSL antenna 101 is formed with Franklin-type strip conductor 1a and earth conductor 1b featuring the width of under the half wavelength. Then MSL antenna 102 containing strip conductor 1b and earth conductor 2b and featuring the plane symmetry to antenna 101 is stuck with antenna 101 back to back via conductors 2a and 2b. Thus a composite antenna is formed. Then feeding points Sa and Sb of these two MSL antennas are excited with the same phase, and as a result the non-directivity and the sharp directivity can be obtained within the horizontal plane and the vertical plane respectively. Also the same-type antenna can be formed even with the crank-type MSL although the non-directivity is sacrificed some within the horizontal plane.
