Abstract: The antenna FM2 comprises a serigraphed aerial on the rear opening window (2) of a station wagon and consists of a defrosting network (4) with two superposed symmetrical vertical lines (5). A thick ground line (8) is serigraphed onto the rear window (2) and a two-wire cable (11, 12) joins the aerial FM2 to an electronic housing (9). On a quarter panel window of the vehicle, the aerial is serigraphed in the form of an F-shape of the servitude antenna and joined by a two-wire cable (19, 20) to an electronic housing (9). The serigraphed antenna for a rear window and for a quarter panel window of a station wagon provides excellent reception in both FM and servitude mode.

Abstract: The aerial of antennas FM1 and FM2 comprises, in addition to the original defrosting network (2), two pairs of vertical lines (9,10) which are disposed symmetrically in relation to the median vertical longitudinal plane of the vehicle. The FM1 signal is collected at a point (12) of the aerial which makes it possible to obtain a directive signal in the direction of the length of the vehicle on a plane with zero height. The FM2 signal is collected at a point (13) which is different from the aerial, making it possible to obtain a directive signal in the direction of the width of the vehicle on a plane with zero height. The serigraphed antenna for the rear window of a salon-type car provides excellent reception for FM, AM and servitude function modes.

Abstract: A dual-band microstrip antenna has a ground plate and also has a central patch positioned between a pair of side patches. The antenna has a single signal feedline, connected to the central patch, and the side patches are shorted to the ground element. Conductive surfaces of the ground plate and patches that carry surface current from signal radiation are contoured such that only portions of conductive surfaces that carry more than a negligible amount of the surface current are retained. The antenna has a reduced weight and improved bandwidth over conventional antennas that operate in the 925 MHz and 1800 MHz ranges.
