Miniature crescent shaped UWB antenna

A miniature ultra-wide band (UVB) antenna is presented. The size of the antenna is 17 mm x 18 mm x 1.575 mm. The antenna radiates at 3.4-20 GHz. The bandwidth of the antenna almost covers the entire UVB of 3.1-10.6 GHz. The size of the antenna is very small. The proposed antenna is fabricated and measured. The experimental results are in a good agreement with the simulated results. (c) 2013 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.
