本文提出了一种有效而简单的k波段微带贴片天线阵列激励方法。该阵列由一个欺骗平面等离子体波导激发和几个圆形贴片辐射组成。优化后的2 x 4贴片阵列，工作频率为18.1，与19.4 GHz相似，平均增益为15.2 dBi， 18.2 GHz时最大增益为16.5 dBi。通过实验验证了设计的有效性。该方法开辟了一种新的贴片天线馈电方式，可广泛应用于毫米波乃至太赫兹区域。
This letter presents an efficient and simple way to excite a microstrip patch antenna array in K-band. This array is formed by a spoof planar plasmonic waveguide for excitation and several circular patches for radiation. The optimized proposed 2 x 4 patch array, operating in 18.1 similar to 19.4 GHz, features an average gain of 15.2 dBi with a maximum of 16.5 dBi at 18.2 GHz. An experiment was performed, and the measured results prove validity of the design. This method opens up a new kind of feeding method for patch antenna array, which can be broadly engineered in millimeter-waves (MMW) region even to terahertz (THz) region.
