A Multi Band Dual Loop Antenna in Millimetric Wave Implementation for 5G Applications

Modern communication technology has proved to be one of the most fruitful advancements in history, which became an essential part of our daily lives. That leads to a highly dense bandwidth and urges for the need of operating at new bands. This paper introduces the simulation and analysis of a Multi Band Dual Square Loop antenna with two different designs, resonating around various frequencies ranging from the 53.7 GHz to the 88.2 GHz, to be utilized in the Millimetric bands. The antennas are designed on a Rogers TMM4 laminate, and the upper dual square loops are made of copper. The simulated results show that the proposed antenna covers a total bandwidth of more than 29 GHz over the V-Band, E-Band and W-Band. Moreover, the return Loss has an average value below the (−0) dB in most regions, and even gets as low as (−49) dB at the 69 GHz. Also, it achieves a gain above 5 dB in most of the bands, and reaches a peak above 9 dB around the 79 GHz. A microstrip feeding technique is used to excite the structured antenna, with an optimized input impedance (Zo) of 50 Ω. Overall dimensions of the Dual Square Loop antenna are 10 mm × 10 mm × 0.762 mm. All of the previously mentioned characteristics make the suggested antenna a potential candidate for several applications in the high bands, the futuristic 5G implementations, unlicensed wireless communication, millimetric wave applications and much more.
