MOBILE COMMUNICATION DEVICE AND ANTENNA STRUCTURE THEREOF

摘要

A mobile communication device having an antenna structure includes a grounding element and an antenna element. The grounding element includes a main ground and a protruded ground being connected to an edge of the main ground. Antenna element includes a feeding portion and a radiating portion. The feeding portion includes a feeding point, a first strip and a second strip. The first strip and the second strip are both connected to the feeding point. The radiating portion includes a first open end, a second open end and a shorting point which is connected to the protruded ground by a short-circuiting strip. There is a first coupling gap between the first strip and a first section of the radiating portion having the first open end. There is a second coupling gap between the second strip and a second section of the radiating portion having the second open end.
