  • Publication number: 20210119346
    Abstract: A reconfigurable antenna apparatus may include an antenna assembly and control circuitry. The antenna assembly may include an antenna patch array having a plurality of antenna patches and a switch array having plurality of switches. Each switch of the plurality switches may be electronically controllable to transition between states including a conducting state and a non-conducting state. Each switch may be electrically connected between two of the antenna patches of the antenna array. The control circuitry may be configured to control the states of the switches of the switch array to operate the antenna patch array in a first communications mode at a first wavelength, and control the states of the switches of the switch array to operate the antenna patch array in a second communications mode at a second wavelength.
