The influences of Complementary Circular Split Ring Resonators (CCSRR) and air gap with accompanying circular microstrip patch are investigated for future wireless communication antenna. It is designed to operate from 5.850 GHz to 7.075 GHz spectrum band using microwave laminate RT/D 5880 ( r = 2.2 and thickness of 1.82 mm). The antenna structure was organized into three separate layers consisting of circular copper sheet as the ground plane (layer number one), an undersized main radiator, where the signal and energy gathered and stored, focuses and passes through to resonate its above layer...
