Abstract :
Simple, approximate formulas describing the peak cross-polar characteristics of circular and rectangular microstrip patches are derived from the governing equations using small argument approximations. Results from the formulas compare favourably with those obtained elsewhere using more stringent numerical methods. In the case of the circular patch, a novel approximation is employed to circumvent the use of Bessel functions
