Abstract :
This paper presents results of comparison of different feeding alignments in quad elements circularly polarised aperture coupled patch antenna arrays. Antennas were designed with parallel and combined feeding. Impedance matching, gain and axial ratio were investigated in more than 10% bandwidth.
