Dual-polarized UWB Antenna System (30 to 100GHz) for Millimeter Wave Communication

A broadband phased antenna array with high gain is considered desirable for millimeter wave communication. In this paper, a tapered slot antenna (TSA) was developed to cover an ultra-wide band from 30GHz to 100GHz. Minor modifications to a classical design is done to improve performance of our antenna. The design was simulated, and the results are presented in this paper. Each antenna element has an average gain of 8.9dBi. This element is used to construct a dual-polarized set to reduce the losses due to cross polarization between transmitting and receiving antenna. An array of 12×12 dual-polarized elements is analyzed. This array is demonstrated to enhance gain while giving the system beam steering and forming capabilities.
