Planar monopole loop composite multi-broadband antenna

A planar monopole loop composite multi-broadband antenna, comprising:

• a carrier;
• a signal line in an asymmetric T-shape formed on said carrier, said signal line comprising a high frequency radiation portion and a first signal line extending from said high frequency radiation portion and coupled to a grounding area, so that a feed point for welding a preset cable is formed at the coupling location;
• and
• a loop grounding line formed on said carrier, said loop grounding line comprising a multi-turn low/medium frequency radiation portion, which surrounds said signal line and comprises an outer loop transmission path and an inner loop transmission path located on one side of said outer loop transmission path and extending inwardly, and a second signal line and a third signal line respectively located at two ends of said outer loop transmission path and coupled to said grounding area, said loop grounding line surrounding said signal line to form a co-planar waveguide feeding monopole antenna having dipole antenna characteristics.
