A Triple T-topped Planar Antenna for 5G/WiMAX Applications

A low-profile triple T-topped planar antenna having a partial ground plane is observed and discussed in this article. The designed antenna can be used for the latest wireless technology 5G communication as well as WiMAX applications. The T-topped antenna is designed by using CST-MWS suite on Rogers RT5880 (2.2, 0.0009) substrate and Copper (annealed) material is used for metallic layers. The height of the dielectric material and metallic layers are 0.79 mm and 0.035 mm respectively. The volume of the triple T-topped antenna is 34 mm × 24 mm × 0.79 mm. The operating frequency range of it is 3.22 GHz-4.25 GHz. The gain and directivity at the resonant frequency of 3.60 GHz are 2.199 dB and 2.720 dBi. It provides a very good reflection coefficient (-56.839 dB at 3.60 GHz), a stable and average efficiency about 89% as well as covers frequency range of 5G communication and WiMAX rel 2 (3.4 GHz-3.6 GHz). Thus the triple T-topped antenna can be a good design for 5G communication and WiMAX applications.
