A Modified Square Patch Antenna with Rhombus slot for High bandwidth

Abstract

Abstract: In this the proposed patch antenna operates at 32 GHz which is among the projected 5G communication frequencies and has a novel geometry with rhombus-shaped slots. The first design in this work is a inset fed used conventionally in patch antenna. It has a quarter wavelength impedance matching line. The dimensions are determined according to the usual design considerations. Low return loss and high bandwidth requirements motivates us to modify the antenna design. Therefore, we add rhombus – shaped slots on the patch which leads to an additional increase in the system bandwidth as much as 52 MHz and a reduction in the return loss level up to 11.241 dB. The proposed patch antenna design is conjectured to be a suitable candidate to address the requirements of 5G communication systems. The operating frequency of the proposed antenna can be tuned by changing the geometrical dimensions from microwave to the THz region.
