Abstract

In this paper, a reconfigurable antenna feeding network using coupled line switches for 5G communication system is presented. Two quarter-wave impedance transformers were integrated to support TDD operation and a single stage coupled line filter was used as a DC block for RF switches instead of using conventional surface mounting components. Design equations and theoretical analysis for the proposed reconfigurable antenna feeding network are also presented. To demonstrate the performance of the proposed reconfigurable antenna feeding system for MIMO, two monopole antennas were integrated orthogonally to the designed feeding network. Vertical or horizontal polarization was successfully formed and the radiation pattern can be selectable by manipulating the switches.
