Abstract:

Conventional microstrip patch antennas are not suitable for modern wireless applications because of their low gain, low directivity, and poor radiation performance. To address these limitations, the patch antenna containing single- and multiple-slots is studied from the perspective of improving performance and its suitability for modern wireless applications. Further, studies were carried out on various slot configurations. The simulated results show that patch antennas containing double- and triple-slotted configurations result in better performance. Among the various slot configurations in the shapes of U, I, and E, the double-slot antenna containing two rectangular slots fixed adjacent to each other in the vertical position showed dual-band operation at 5.12 GHz and 6.8 GHz, with gains of 4.88 dB and 3.22 dB, respectively. Furthermore, the triple-slot antenna configuration showed high gain and good directivity with a single resonant frequency of around 5 GHz. The simulation is carried out using HFSS software.
