两个频率选择表面 (FSS)，每个表面有 12 个贴片元件；已被用来将扩展尺寸的微带贴片天线在 X 频段 (8-12 GHz) 频率下的增益提高至 18.5 dBi。只需在电场辐射上添加两个反射器，天线增益就进一步提高到 19.2 dBi。首先从数学角度检验增益增强的概念，并使用基于 CST 微波工作室模拟的数值方法对其进行分析。所提出的两种高增益天线均已在 10 GHz 左右的频率下制造和测试。测量结果和仿真结果吻合良好。
Two frequency selective surfaces (FSSs), each with 12 patch elements; have been exploited to enhance the gain of an extended size microstrip patch antenna up to 18.5 dBi at X‐band (8‐12 GHz) frequencies. The antenna gain is further improved to 19.2 dBi just by adding two reflectors across E‐field radiation. The concept of gain enhancement is first examined mathematically and them it is analysed with numerical method based on CST microwave studio simulations. Both of the proposed high gain antennas have been fabricated and tested at around 10 GHz frequencies. The measured and simulation results showed a good agreement.
