本文对差分激励下正三角形微带贴片天线带宽增强的机理进行了全面的研究。由于采用了差分激励的方式，这种贴片中TM 11模的辐射方向性得到了很大的改善，并且TM 10和TM 11模的场分布被同时激励辐射。接下来，将两个短路柱引入到该MPA，以便产生附加模式，即，零模，其在TM 10和TM 11模之间的频率上谐振。这三个模式的适当安排，在彼此接近，可以令人满意地实现了较宽的辐射带宽。为了证明所提出的概念的有效性，一个原型天线的最后设计和制造。如理论预期，最终设计的贴片天线的阻抗带宽已增加到50.46%，增益约为6.5 dBi。仿真和实测结果均显示出较宽的带宽和良好的辐射性能。
A comprehensive study on the mechanism of bandwidth enhancement for an equilateral triangular microstrip patch antenna (MPA) under differential excitation is presented in this paper. Attributing to the way of differential excitation, the radiation directivity of TM11 mode in such a patch has been improved a lot, and field distributions for both TM10 and TM11 modes are found to be simultaneously excited for radiation. Next, two shorting posts are introduced to this MPA so as to generate an additional mode, i.e., zero mode, which resonates in a frequency between TM10 and TM11 modes. With the proper arrangement of these three modes in proximity to each other, a wide bandwidth for radiation can be satisfactorily achieved. To demonstrate the validity of the proposed concept, a prototype antenna is finally designed and fabricated. As theoretically expected, the impedance bandwidth of the final designed patch antenna has been increased to 50.46% and the gain is around 6.5 dBi. Both simulated and measured results exhibit wide bandwidth and good performance of radiation.
