Abstract :
The authors present a new printed cylindrical slot antenna for GPS commercial applications. This antenna displays compact size, low cost, ease of mass production, near-hemispherical radiation coverage and circular polarisation properties. Experimental results show that the printed cylindrical slot antenna has a 3 dB beamwidth of 120° and a front-back ratio >15 dB
