Abstract

A new shape of slot antenna (U-shaped) is introduced in this paper. The proposed antenna is designed for use in mobile phone devices. This structure covers bands ISM/Bluetooth, WLAN, Wi-Fi, WiMAX, 5G applications, cellular communications, weather radar, surface ship radar, and some communications satellites. A U-shaped slot is cut on the ground plane. A coupling feed technique is used to feed the designed antenna. The proposed antenna is printed on a high-loss FR-4 dielectric substrate with . The designed antenna achieves a very wide bandwidth (from 2.3GHz to 6.3GHz). A high gain (around 7dB) is also achieved. The design is simulated using CST software, and the results are verified by HFSS software.
