ABSTRACT:
A dual-frequency high-gain antenna is provided, which includes: a diplexer loop portion disposed at the center of the antenna substrate for receiving a feed signal; two single-frequency radiation units, symmetrically connected to two sides of the diplexer loop portion for radiating a radio-frequency signal corresponding to a first frequency value of the feed signal; and two dual-frequency radiation units, respectively connected to each single-frequency radiation portion for radiating radio-frequency signals corresponding to the first frequency value and a second frequency value of the feed signal.
