Improved Performance in Compact Antenna by Using E-slotted and DGS for V and E band 5G Applications

Recently, demand for fifth generation (5G) wireless communication is very high due to its bandwidth-efficient and high data rate. Thus, a high-performance microstrip patch antenna (MPA) is required to be designed. In this paper, we propose a compact E-shaped MPA for the V and E band and backhaul applications. The proposed antenna has small size dimensions of 3 × 2.9 × 0.508 mm3 and a low-cost Rogers/RT Duroid is used as a substrate material with a loss tangent of 0.0012. E-shaped slots and Defected ground structure (DGS) are implemented on patch and ground, respectively. Both techniques are used to improve the performance of the proposed antenna in terms of bandwidth and return loss. This achieves 14.56 GHz bandwidth from 63.05-77.61 GHz with a gain of 7.11 dB and return loss of −45.71 dB at centered frequency equals 66.33 GHz. For further enhancement, the insert feed technique is used. As a result, the proposed design has a good performance in terms of antenna return loss, gain, bandwidth, characteristics impedance, and high efficiency at the resonant frequency. Therefore, it can be a candidate for V and E band and backhaul outdoor environments applications. Higher Frequency Structural Simulator (HFSS) tool is used for simulation.
