Brick-wall antenna fed by CPW

A brick-wall antenna fed by a coplanar waveguide (CPW) is introduced. This antenna can be considered as an eleven elements array with reduced size. The analysis is being carried out both theoretically and experimentally. The proposed antenna is designed to work around 9.5 GHz. The presented results include the return loss and the radiation patterns. It has several advantages such as the ease of fabrication, good control of its input impedance, small cross polarization level, and high directivity.
