Microstrip antenna for two-frequency separate-feeding type for circularly polarized waves

摘要: A microstrip antenna of two-frequency separate-feeding type for circularly polarized waves is disclosed, in which four radiation conductors are disposed on a dielectric plate mounted conducting ground plane and each conductor has its marginal portion partly short-circuited via short-circuiting to the supplied at feeding point with power feeder passing through plate. The composed two pairs different sizes adjusted so that desired frequencies can simultaneously be used transmission reception, respectively, pair being arranged generate wave.
