Design of a combined horizontal and U slot patch antenna with reduced cross-polarization and increased sustainability

Abstract

This paper presents a rectangular microstrip patch antenna designed to operate at a frequency of 2.6348 GHz. The antenna is equipped with a U-slot and horizontal slot to mitigate cross-polarization effectively. By strategically placing the U-slot on the radiating patch and incorporating a horizontal slot on the patch, the antenna achieves enhanced radiation characteristics. It demonstrates excellent impedance matching with a VSWR of 1.02, indicating minimal signal reflection (S11 of -27.47dB) and improved transmission efficiency with a gain of 7.11dBi. The proposed design offers reduced cross-polarization characteristics and increased sustainability with compact size, making it suitable for WLAN applications prioritizing reliable and efficient communication.
