Abstract
Abstract A microstrip line –fed broadband dual circular polarized, two port printed monopole antenna is presented. The antenna consists of a ground plane with arrow shaped stub at the corner and a pair of inverted L-shaped feed lines. The 3dB axial ratio bandwidth of the antenna is about 58%(1.7GHz-3.1GHz) in which the return loss and isolation are better than 10dB and 12dB respectively. A parametric study of proposed antenna’s geometric parameters is given for understanding of the antenna performance. The realize gain, reflection coefficient (S 11 ) and transmission coefficient (S 21 ) are higher than 1, 10 and 12dB respectively within the entire axial ratio bandwidth (ARBW).
