Antenna structure

Abstract

An antenna structure includes: a first radiating section, a loop radiating section, a second radiating section, a third radiating section, a fourth radiating section, and a carrier element. The first radiating section has a feed point. The loop radiating section is coupled to the first radiating section. The second radiating section is coupled to the first radiating section, wherein the second radiating section is adjacent to the loop radiating section. The third radiating section is coupled to a ground potential, wherein the third radiating section is adjacent to the first radiating section. The fourth radiating section is coupled to the third radiating section, wherein the fourth radiating section is adjacent to the loop radiating section. The first radiating section, the loop radiating section, the second radiating section, the third radiating section, and the fourth radiating section are all disposed on the carrier element.

Claims
