Use of Slots in Bandwidth enhancement of microstrip patch antenna for 5G mobile communication networks

Recent studies have centered on finding the most effective methods for increasing the gain, directivity, and bandwidth of a microstrip patch antenna for usage in a variety of wireless applications. Microstrip patch antennas (MPAs) have been presented as a space-efficient and low-profile method of achieving a wide frequency range by employing slots of varying shapes. To demonstrate the concept behind the proposed antenna, parametric simulations were carried out. To increase bandwidth, many slots have been added. The slots are set up in the form of an RAED on the patch. The Rogers RT Duroid 03003 substrate is used in both the design and simulation processes for the proposed antenna. This substrate has a standard thickness of 1.52 mm, a relative dielectric constant of 2.2, and a tangent loss of 0.0009 at the operating frequency. Simulated findings reveal a return loss of -62.247 dB, bandwidth of 11.031 GHz, and gain of 6.48 dBi at a central frequency of 28.427 GHz. The proposed antenna has a nearly 10-fold improvement in bandwidth over the MPA without the slots. This demonstrates how antenna slots greatly enhance gain and bandwidth. Therefore, the suggested antenna's compact design makes it well-suited for 5G mobile communication networks.
