Abstract :
This paper presents the experimental results of two dual linearly polarized aperture coupled microstrip ring antennas operating at 1.8 GHz. The use of multiple feeds has resulted in measured input isolation of -30 dB and cross polarization radiation levels of up to -25 dB down from the co-polarization.
