摘要： An antenna comprises a linear antenna element 10 with one end connected to a feed 15 and the other end connected to at least one end of at least one arm element 20, where the other end of the or each arm 20 is open circuited and where the antenna is arranged to resonate at a higher order mode of a target frequency. The higher order mode may be an odd mode such as the third order mode of a target frequency. Alternatively, the said mode may be an even mode, such as the second order mode, where an impedance transformer is provided at the feed to the antenna. The, or each, arm element 20 may be tilted relative to the longitudinal direction of the linear antenna element 10. Various numbers of arm elements 20 may be used, for example one, four or eight arm elements 20 are disclosed. The arm elements 20 may be evenly distributed and may be of various shapes such as straight, helical or meandering. The antenna may be arranged to form a dipole antenna formation. The antenna is intended to provide a compact antenna with good gain and directional operational characteristics.

摘要： A vehicle antenna is concealed by utilizing, an elongated slot normally functioning only for decoration on a metal panel of the vehicle. A basic form of the antenna is a slot antenna in which a wire extends across the slot through or behind an opaque plastic plug fitted in the slot and extending in the plane of the metal panel. Plastic bumper moulding or vehicle trim may have a stem portion that is press-fittable in the slot for retaining the moulding or trim in place on the vehicle, and in such case the stem portion may be a dielectric material to an end of which an antenna element can be fitted.

摘要： An integrated antenna includes a dielectric on which is patterned an antenna element and on which, close to an edge of the dielectric, is also patterned a conductive ground coupling member. The ground coupling member is capable of electricalcoupling with a grounded body surrounding the dielectric to provide a ground for an unbalanced transmission line whose live is connected to the antenna element. The length of the ground coupling member is made such that an integral odd number of quarterwavelengths of signals at each operating frequency are adapted to extend either side of a signal-ground connection point; the length approximates one-half wavelength at the primary operating frequency. By including a second signal feedline to extend in parallel with the ground coupling member and connect with another antenna element, it is possible for the integrated antenna to receive/transmit on at least two frequencies. The invention finds application in integrated antenna structures in which a local ground connection is not readily possible. For instance, the dielectric and grounded body may be a respective window and chassis of a car. Another automotive application involves forming the integrated antenna on a plastic boot lid.

摘要： A vehicle windowpane antenna apparatus comprises a defogger (10) for defogging a vehicle window (100), which is constituted of a strip conductor at least including a plurality of horizontal wires (10a) and a pair of bus bars (10c, 10d), the bus bars (10c, 10d) being arranged on a window glass surface (110) and each opposed to a metal section (120M) of a window frame (120) with a bus-bar gap (BG) therebetween, a unit (14A, 14B) for separating the power source line (13) and the defogger (10) from each other in a high-frequency manner, vertical wires (10b) crossing the horizontal wires (10a) to form the defogger (10) in a mesh pattern having meshes, a length (Lx) of a longer side of each of the meshes being smaller than a wavelength of received wave, and a driven antenna (20) having a height (H) and provided close and opposite to the defogger (10) with a clearance (CG) therebetween in such a manner that one side (20a) of the driven antenna (20) is mutually coupled (MC) to one side (10U) of the defogger (10), the bus-bar gap (BG) being set to 50 mm to 70 mm, the clearance (CG) being set to 5 mm to 15 mm, the height (H) being set to 100 mm to 250 mm, the number of vertical wires (10b) being one or more, and the power source line (13) and the bus bars (10c, 10d) constitute an open circuit (OC) therebetween.
