Closed-form model to determine the co-axial probe reactance of an equilateral triangular patch antenna.

A simple closed-form analytical formula is proposed to compute the probe reactance of an equilateral triangular patch antenna. The variation of the probe reactance with the variation of antenna dimension, substrate electrical parameters, and probe location is examined thoroughly. The computed values employing the present model show excellent agreement with experimental and simulation results. [ABSTRACT FROM AUTHOR]
