Abstract

This paper presents a broadband printed circularly polarized monopole antenna. The base antenna consists of a falcate-shaped monopole antenna which provides 43% axial ratio bandwidth. By inserting a falcate-shaped slot in the base patch, 56% axial ratio is obtained. Moreover, inserting a slot in the base patch has no effect on the impedance bandwidth of the original structure. The proposed antenna dimension is 40 × 46 mm² and is fabricated on 1 mm FR4 substrate. The simulated return loss and axial ratio bandwidth of the antenna structure with and without the falcate shaped slot are presented and compared. Moreover, circular polarization radiation patterns of the proposed antenna are presented.
