Abstract :
In this paper, a novel stacked microstrip antenna (MSA) is proposed for wideband circular polarization. The antenna consists of two rectangular patches with two orthogonal slots at the center of each patch. The lower patch is excited with a coaxial line. The normalized bandwidths of the input impedance and axial ratio (AR) of the proposed antenna are found to be 17% and 13% respectively. Also, comparing the proposed antenna with a similar structure but without any slots, it is found to be 10% more compact. The proposed antenna is simulated using commercial electromagnetic software IE3D which is based on the method of moment (MoM).
