表明这种分析方法是有效的.

Abstract

Microstrip patch antenna with a shorting pin has a lower resonant frequency

so it especially suits to low frequency portable communication equipments(such as handsets).Compared to rectangular and circular patch antenna loaded with a shorting pin

triangular patch antenna loaded with a shorting pin has lower resonant frequency.Based on the cavity model theory

this paper used the static mode of the unloaded triangular patch antenna to propose the analytical method of triangular patch antenna loaded with a shorting pin

and the calculation formulas of resonant frequency、input impedance and reflective loss for this kind of antennas are given.The numerical calculations agree with the measured results very well

verifying that this analytical method is valid.
