Wideband Millimeter-wave Microstrip Array Antenna with Stable Radiation Pattern for Advance High Bandwidth Wireless Communications

A wideband 3 elements array antenna based on single layer mm Rogers RT5880LZ substrate (Epsilon of 1.96 and Loss Tangent of 0.0019) for advance Millimeter-wave (MMW) communication is proposed in this paper. Radiation of a main and two subsidiary array elements lead to an excellent bandwidth of 24.3 GHz. Surface current, total efficiency, antenna radiation patterns at 44 GHz,48 GHz, 52 GHz, 56 GHz, 60 GHz and 64 GHz frequencies are shown and discussed. Stabile radiation pattern during whole bandwidth, wide bandwidth, high total efficiency and small patch structure make the antenna an appropriate candidate for compact wireless systems.
