變形圓微帶天線諧振頻率的研究
RESEARCH ON RESONANT FREQUENCY OF DEFORMED CIRCULAR MICROSTRIP ANTENNAS

摘要: 微帶天線的窄頻帶在很大程度上限制了它在許多方面更廣泛應(yīng)用。如何展寬其頻帶一直為國內(nèi)外學(xué)者所關(guān)注。本文用變分法并結(jié)合微擾理論分析了一種變形圓貼片寬頻帶微帶天線的諧振頻率。理論計算值與實測結(jié)果一致性較好,為微帶天線諧振特性的綜合奠定了一定基礎(chǔ)。

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. -
