Patent ID: 10727596

Abstract:
An antenna structure (10) includes an antenna feed-in element (1), a first antenna trace element (2), a second antenna trace element (3), a supporting element (4), a grounded-short-circuit element (5), a third antenna trace element (6) and a fourth antenna trace element (7). The first antenna trace element (2), the second antenna trace element (3), the third antenna trace element (6) and the fourth antenna trace element (7) which have vertical segments in different lengths form a multi-trace planar inverted-F antenna to obtain the best bandwidth covering the full band, so that the height of the antenna structure (10) is lower, the length is shorter and the structure is denser. The impedance matching of the antenna structure (10) is controlled easily. No external matching element is required. With the multi-trace and grounded-short-circuit design of the antenna structure (10), the better resonance in the LTE full band is obtained.
