Abstract :
An L-band, circularly polarized, dual-feed, cavity-backed annular slot antenna has been investigated. The investigations comprise parametric studies of design parameters and measurements with different ground planes. The antenna has an impedance bandwidth of 6% around 1.59 GHz and a maximum directivity of about 7 dBi
