This invention discloses a bandwidth-reconfigurable dual-polarized dielectric patch antenna for full-duplex communication. The antenna consists of a rectangular dielectric patch with a pair of grooves etched along its edges and two substrate layers.

For the Y-polarization direction, a differential feed structure is used to excite a degenerate TM. 01 Mode and Inversion™ 02 This mode is used for broadband receiver operation. A metal ground plane is placed between two substrates, and two sets of slots are etched on it for aperture coupling between the dielectric patch resonator and the metal microstrip line located at the bottom of the lower substrate.

This gives the antenna advantages such as bandwidth reconfigurability, high isolation, low profile, and simple structure, making it promising for applications in full-duplex systems.
