摘要: 微带天线的窄频带在很大程度上限制了它在许多方面更广泛应用。如何展宽其频带一直为国内外学者所关注。本文用变分法并结合微扰理论分析了一种变形圆贴片宽频带微带天线的谐振频率。理论计算值与实测结果一致性较好,为微带天线谐振特性的综合奠定了一定基础。Abstract: On account of narrow bandwidth, many applications of microstrip antennas are limited in great degree. How to widen its bandwidth is being concerned by lots of scholars at home and abroad. In this paper, resonant frequency of the deformed circular microstrip antennas is investigated based on variational principle and the perturbation concept. The theoretical results are found to be in reasonable agreement with the experimental ones for small modified element. This paper provides a theoretical and experimental bases for the synthesis of microstrip antennas.
