An UWB Antenna: A Design for Wide Range Perspective

摘要

In this paper, the design, simulation, and experimental validation of an ultra-wideband (UWB) printed antenna is presented. Initially, a microstrip fed is implemented to provide the input impedance of 50-ohms. After that, the two consecutive L-shape metallic slots that are implemented at the top of the design. The advantages of inserting these metallic slots are playing a vital role to achieve better the resonant frequency and improve impedance bandwidth. Additionally, two L-shape open slots are etched on the ground part of the design. These slots are playing another vital role to enhance the impedance bandwidth. Besides, a metallic L-shape slot implemented between two open slots on the ground part of the antenna. The measured results show a 10-dB impedance bandwidth (IBW) of 9.2 GHz (122.67 %) at the mid-band frequency. The maximum measured gain and efficiency of the designed antenna is 6.2 dBi and 98 %, respectively. The simulated and measured results of return loss, peak realized gain, efficiency (simulated only), and radiation pattern are verified. So, the experimental results in good agreement with the simulated one.
