Double-frequency printed single-pole antenna

The invention provides a double-frequency printed single-pole antenna which comprises a transmission line, a first radiator and a second radiator. The transmission line extends along the first direction, and comprises a first end and a feed-in end, wherein the feed-in end is arranged adjacent to the first end. The first radiator is connected with the first end, and extends along the second direction, the width of the first radiator gradually changes, the second direction is vertical to the first direction, and the first radiator is operated within a first frequency range. The second radiator is connected with the first end, extends along the third direction and includes multiple turns, the third direction is the direction far from the grounding end, a first included angle is formed between the third direction and the transmission line, and the second radiator is operated within a second frequency range.
