Design of a Miniaturized Quarter-circular-slot UWB Antenna

A miniaturized quarter-circular-slot UWB (QCS-UWB) antenna using field-pattern analysis of the circular-slot UWB prototype antenna is proposed. Even though the proposed antenna has only the quarter part of the prototype antenna it maintains UWB antenna characteristics. The measured gain of the miniaturized antenna from 3.0 GHz to 12.0 GHz is within -0.1 dBi ~ 1.6 dBi, which is comparable to the prototype antenna’s gain, -2.7 dBi ~ 3.1 dBi.
