Abstract :
A scannable, broadband, circularly polarised microstrip patch array suitable for satellite communications is presented. The low profile array consists of eight hi-lo stacked patches and a simple feed arrangement to generate circular polarisation. The 10 dB active reflection coefficient of the array is greater than 28% at broadside and the array has a measured axial ratio less than 3 dB for scanning to ±450 over this frequency range.
