Circular Shaped Ultrawide-Band Antenna for Wireless Communication

Abstract

This paper presents the design of (UWB) antenna with asymmetrical U-Slot, operating in the microwave band of (3.5-15) GHz. This design permits its applications in various sectors, such as wireless communications, radar systems, and remote sensing. The antenna is covering bandwidth of (11.5) GHz with gain of (6.298) dB at (14.25) GHz. The substrate used is (FR4 Epoxy) of (????_????=4.4), loss tangent of (0.02), and thickness of (1.575) mm. The extensive bandwidth of the antenna makes it operate in both the C-Band and X-Band. Overall, the design of this (UWB) antenna aims to provide a high-performance antenna that can operate over a wide frequency range, making it suitable for various applications.
