Compact UWB planar antenna for broadband applications

In this paper, a planar antenna for broadband applications has been proposed. The antenna consists of a rectangular patch, a partial ground plane and a slot on the ground plane. The proposed antenna is easy to be integrated with microwave circuitry for low manufacturing cost. The flat type antenna has a compact structure and the total size is 14.75 ×14.5mm. The result shows that the impedance bandwidth (VSWR ≤ 2) of the proposed antenna is 12.87 GHz (3.02 to 15.89 GHz), which is equivalent to 136.12%. Details of the proposed compact planar UWB antenna design is presented and discussed.
