Improvement in the antenna gain is usually achieved at the expense of bandwidth and vice versa. This is where the realization of this enhancement can be made through compromising the antenna profile. In this work, we propose a new design of incorporating periodic metasurface array to enhance the bandwidth and gain while keeping the antenna to a low-profile scheme. The proposed antenna was simulated and fabricated in order to validate the results in the operating frequency range from 10 MHz to 43.5 GHz. Computer simulation technology (CST) microwave studio software was used to design and simulate the proposed antenna, while LPKF prototyping PCB machine was utilized to fabricate the antenna. Results showed that the antenna generated a gain and bandwidth of 14.2 dB and 2.13 GHz, respectively. Following the good agreement between the numerical and measurement results, it is believed that the proposed antenna can be potentially attractive for the application of satellite communications in Ku-band electromagnetic wave.

基于单层超颖表面的Ku频段低剖面天线

通常以带宽为代价来实现天线增益的提高，反之亦然。在此可以通过损害天线轮廓来实现这种增强。在这项工作中，我们提出了一种结合周期性超表面阵列的新设计，以提高带宽和增益，同时使天线保持低调方案。为了验证在10 MHz至43.5 GHz的工作频率范围内的结果，所提出的天线经过了仿真和制造。使用计算机仿真技术（CST）微波工作室软件来设计和仿真所建议的天线，同时使用LPKF原型PCB机制造天线。结果表明，该天线分别产生了14.2 dB和2.13 GHz的增益和带宽。
