Abstract :
A new combination of aperture coupled microstrip antenna and metamaterial cover structure is applied to achieve 10.5 dB gain. We also report an integration of conical frame with aperture coupled microstrip antenna to increase the gain from 5.7 dBi to 12.2 dBi and a bandwidth of 12.2% over 11.05 GHz - 12.5 GHz. The presence of the metamaterial cover and conical frame has improved the back-lobe level by 4.8 dB and 6.5 dB respectively. The antenna is designed in the Ku-band.
