Millimeter waves (mm-Waves) can offer large spectrum bandwidths, provide data rates of multi-Gbps and enable seamless connectivity among various devices in the future wireless network (5G and beyond). Incorporating mm-Wave microstrip antennas in 5G networks will be highly instrumental which provides the advantages of miniaturization, wider bandwidth, narrow radiation pattern, and are better suited for the data rates enhancement with lower delays. In this paper, a low cost, compact size and bandwidth efficient dual-band rectangular microstrip patch antenna is proposed for 5G mm-Wave wireless access and backhaul applications. The antenna has a small size of 7.18 × 8.38 × 0.78 mm3. The design has been carried out at 35.786 GHz (Ka band) and 72.709 GHz in the E-band of mm-Wave spectrum, with large bandwidth of 10.435 and 6.705 GHz respectively. The 5G dual-band antenna has a sufficient realized gain of 8.01 and 8.52 dBi and achieves return loss of −19.833 and −30.314 dB at the resonant frequencies. The proposed antenna design can be further extended to be an antenna array of multiple elements to satisfy application requirements and improve the different antenna parameters such as gain, directivity, bandwidth and VSWR. |
