Abstract (en)
A compact patch antenna for use in an antenna array in a wireless telecommunications network. The patch antenna is operable to receive a feed signal and transform that feed signal to a radiated output signal. The compact patch antenna comprises: a ground plate and a radiating element operable to radiate the output signal. The radiating element is located substantially parallel to, and spaced from, the ground plate. The antenna further comprises a capacitive loading element extending from the ground plate. The loading element is arranged to define a cavity between the radiating element and the ground plate, and is spaced from the radiating element to define a predetermined capacitive gap between the radiating element and the capacitive loading element. The predetermined capacitive gap is selected to alter capacitance of the cavity. The antenna also comprises a differential signal feed mechanism operable to couple the feed signal to the radiating element, and alter inductance of the cavity in a predetermined manner selected to substantially compensate for a reduction in output signal bandwidth caused by the alteration to the cavity capacitance caused by the predetermined capacitive gap.
