CP microstrip antenna with wide beamwidth for GPS band application

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 0.12 only and exhibits a 3dB axial-ratio be...

Summary: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 0.12 only and exhibits a 3dB axial-ratio beamwidth of more than 130 deg . The experimental results for operating in the 1575MHz GPS band are presented and discussed.
