Novel design of Multiband Slotted and Miniaturized Microstrip Patch Antenna for X and Ku -band Applications

Abstract

This article takes a research on a novel design of a multiband slotted microstrip patch antenna. It depicts a multi ultra wideband compressed and developed antenna with double F- slots, four rectangular slots, and side corner cuttings on the patch using partial Ground. The proposed multiband microstrip patch antenna can resonate at six unique frequencies between 8 GHz and 19 GHz in X and ku bands and execute the reflected power of − 23.8351 dB, − 32.9380 dB, − 14.6726 dB, − 22.2810 dB, − 19.0592 dB, and − 18.8137 dB at 8.6181 GHz, 12.3116 GHz, 14.1960 GHz, 15.6281 GHz, 18.1910 GHz, and 18.9447 GHz, respectively. The gained voltage standing wave ratio (VSWR) is less than 1(0.3918). A maximum directivity and gain of 6.9104 dB and 6.3769 dB is achieved at the resonating bands. Moreover, the effectiveness of the proposed multi-band patch antenna has been verified through the radiation pattern and radiation efficiency of measured results. The low size, weight, and cost of the geometry of this antenna make it entice for Radar engineering, police radars for measuring the speed of the vehicles, for military applications, for navigation intentions, and in finding out the weather forecast and Satellite broadcast communication, space-crafts, wireless computer networks, etc.

Enhancing Patch Antenna Performance through the Integration of Inverted U-Slots

“…To address these challenges and improve their performance, inventive techniques such as Defected Ground Structures (DGS) [19,20] and slot cutting methods [21] have been developed.…”
