Millimeter wave printed antenna array with high side lobe suppression

In this paper we introduce new millimeter wave antenna array with relatively high gain of 20.8 dBi and high side lobe suppression. The antenna consists of axial array placed between corner reflector plates. The antenna is designed and realized in the frequency range about 26 GHz which is popular for microwave communication networks. Side lobe suppression in both H- and E-plane is better than 32 dB. The bandwidth of the antenna is wider than 15% and losses are about 1 dB. The antenna is suitable for integration with other microwave circuits. Agreement between simulated and measured results is very good. The presented antenna is low cost and very simple for realization
