A compact ultra‐wideband antenna with three C‐shaped slots for notched band characteristics

In this paper, a compact UWB (ultra‐wideband) antenna with three C‐shaped slots for notched band characteristics is presented. The proposed antenna covers a bandwidth between 2.95 GHz and 12 GHz. Three different sizes of C‐shaped slot are integrated in the radiating element to remove three frequency bands at WiMAX (3.2‐3.8 GHz), C‐band (3.7‐4.2 GHz), and WLAN (5.15‐5.85 GHz). The antenna has a compact size (30 × 30 mm2). The simulated results show good and acceptable agreement with measurement results in terms of S‐parameters and radiation patterns.
