BROADBAND CYLINDRICAL CORNER REFLECTOR FOR 2.4GHZ WIFI BASE STATION APPLICATION

Directional antenna for WiFi base station is an emerging field of research. In this work a novel directional antenna based on Cylindrical Corner Reflector (CCR) fed by printed strip dipole is presented. The antenna demonstrates a linearly polarized high gain 12dBi with impedance BW of 310Mhz, and HPBWH of 57o . Two parasitic elements were added along the main dipole strips to broaden the bandwidth and to cover other 3GPP frequency bands for 3G/4G wireless communications. 1.25GHz bandwidth was obtained with a consistent radiation patterns for E and H planes. The proposed antennas is simulated and optimized using the FEM based EM solver, the return loss, radiation patterns and input impedance were investigated. Fabrication of the prototype and experimental results were also presented. The Experimental and simulations results were found of a good agreement.
