Abstract :
Experimental results are presented on dual linearly polarised aperture-coupled microstrip ring antennas operating at 1.8 GHz. The introduction of multiple feeding points has resulted in the achievement isolation between the two ports of 30 dB with cross-polarisation radiation levels of better than 25 dB at boresight relative to the co-polarisation
