Abstract :
This paper presents a technique developed for increasing the beam width of the circularly polarised (CP) radiation. With a pyramidal ground structure and a partially enclosed flat conducting wall adopted the designed CP patch antenna has a height of about 0.121 only and exhibits a 3 dB axial-ratio beamwidth of more than 130deg. The experimental results for operating in the 1575 MHz GPS band are presented and discussed.
