Low-profile Flexible Perovskite based Millimetre Wave Antenna

This paper presents the potential of perovskite antenna in the millimeter band. New materials have been developed to obtain suitable chemical characteristics to offer several advantages including simple structure, high operating bandwidth, high gain, compact and low-profile antennas in the millimeter range. The performance of antennas fabricated using these materials is analyzed here. Simulated results of the antenna prototype show a wide bandwidth of 26-33 GHz. Moreover, simulation evaluation of peak gain of the antenna is 1.443 dB at 28.8 GHz. Low efficiency of 45% in the range of operation presents as the main drawback of this design. The analysis is further extended to examine the impact of different flexible substrate materials. The thickness of the patch is also examined to optimize the antenna radiation performance.
