偏心環(huán)微帶天線諧振特性的研究
ANALYSIS OF RESONANT CHARACTERISTIC ON ECCENTRIC RING MICROSTRIP ANTENNAS WITH ARBITRARY SHAPE
-
摘要: 本文用點(diǎn)匹配法分析了偏心環(huán)微帶天線的諧振特性,所得公式可將圓形、同心圓環(huán)和偏心圓環(huán)微帶天線作為特例來(lái)應(yīng)用.對(duì)偏心圓環(huán)諧振波數(shù)的理論計(jì)算與實(shí)驗(yàn)測(cè)試的良好一致性表明,這種方法適用于分析任意形狀微帶天線的諧振特性.偏心圓環(huán)較之同心圓環(huán)有較寬的帶寬.

Abstract: Resonant characteristic of eccentric ring microstrip antennas has been studied using point-matching moded. The formulation can be appplied to some specific cases, for example, circular, circular ring and eceentric circular ring patch antenna. The good agreement between measured and calculated results of resonant wave-number of eccentric circular ring microstrip antenna indicates that the method can be used to analyse characteristic of arbitrary shape microstrip antennas. -
