Abstract:
In this paper, a low-cost polycarbonate substrate is used for the design of antennas operating in the 28 GHz band. First, a corner bent inset fed patch antenna is proposed with a forward gain of 7 dBi and a front to back ratio of more than 18 dB indicating minimal radiation towards the user post-integration with a mobile terminal. In order to cater to the landscape mode, a corner bent tapered slot antenna is also proposed with a gain of 7 dBi. An overlapped architecture is investigated to demonstrate orthogonal pattern diversity with an effective radiating volume of 0.12λ03, a port to port distance of 0.13λ at 28 GHz, and mutual coupling of less than 27 dB without deterioration in the pattern integrity of the corresponding modes. Detailed simulated and measured results are presented with justification.
