Antenna Theory .com The axial ratio is the ratio of orthogonal components of an E-field. A circularly polarized field is made up of two orthogonal E-field components of equal amplitude (and 90 degrees out of phase). Because the components are equal magnitude, the axial ratio is 1 (or 0...

Calculate the axial ratio of an equiangular spiral antenna at azimuth=0 and elevation=0. s = spiralEquiangular; ar = axialRatio(s,3e9,0,0) ar = Inf Axial Ratio of Cloverleaf Antenna Create a cloverleaf antenna. cl = cloverleaf; show(cl); ...
In this letter, we propose a circularly polarized (CP) square antenna that can change the frequency of the minimum axial ratio (AR). The proposed antenna is designed in a very straightforward manner by applying four long stubs to a square patch. The length of one of the stubs is different...
