Abstract
A broadband circuit shorted resonant patch antenna, it is provided with an open circuit end and a short circuit end; the open circuit end has open slots of which an electric field radiates. Path of electric current of the circuit shorted resonant patch antenna from the open circuit end to the short circuit end is extended to lower the resonance frequency, and a compensating device is used to perform broadband compensation to maintain the bandwidth in use. The short circuit end can be partially shorted to extend the path of electric current. The broadband compensation can be done with a resonance circuit or a transmission line. Thereby, length of the circuit shorted resonant patch antenna can be shortened to form a miniaturized patch antenna.
