Abstract (en)
[origin: EP0795926A2] The antenna is built up in three planes with a baseplate (1) defining one plane as the wall of a metal box or the metallisation on a circuit board. The slot distributor in another plane is a U-shaped metallic strip with a quarter wavelength centre portion (2) and two limbs (3,4), each of one-eighth of a wavelength long and short circuited (5,6) to the baseplate. The resonant structure in the third plane comprises two symmetrical plates (9,10) separated by a gap (11). The feeder is a strip line (7) joined by a leg (8) to a coaxial connection under the baseplate, or to a microstrip line on a circuit board.
