Abstract :
A new combination of proximity coupled circular microstrip antenna and integrated square quasi-planer surface mounted short horn (SMSH) is proposed for high gain with circular polarization. The circular polarized gain is 10.02 dBic, axial ratio (AR) is 0.1 dB and 3 dB AR bandwidth is 2.22% from the newly proposed circular dumbbell crossed- slots in patch antenna on low permittivity substrate. The total thickness of the antenna is only 12.58 mm.
