A CPW-Fed slotted monopole antenna for X-band applications

A miniaturized coplanar waveguide (CPW)-fed slotted monopole antenna is presented. The proposed antenna has small size, excellent radiation characteristics and circularly polarization. Slotted monopole antenna surrounded by upper and lower ground plane sections that are interconnected by the microstrip line. These monopole antennas require a relatively large ground-plane structure that can be of various configurations typically in the shape of a square, rectangle, circle, or ellipse. In this paper, a relatively small wideband monopole antenna is presented for X-band applications.
