Abstract

The invention relates to a multi-band built-in antenna, which comprises a horizontal branch, a vertical branch, a metal feed tape (3), a ground metal tape (4) and a substrate ground plane (5). The horizontal branch comprises a horizontal branch I (101), a horizontal branch II (102) and a horizontal branch III (103). The vertical branch comprises a vertical branch I (201), a vertical branch II (202), a vertical branch III (203) and a vertical branch IV (204). The horizontal branch I (101) and the horizontal branch II (102) are connected through the vertical branch I (201), the vertical branch II (202) and the vertical branch III (203). The horizontal branch II (102) and the horizontal branch III (103) are connected through the vertical branch IV (204). The horizontal branch III (103) is connected with the substrate ground plane (5) through the metal feed tape (3). The multi-band built-in antenna of the invention has small volume and low effective height.

Description

(1) Technical field [0001] The invention relates to an antenna, in particular to a multi-band built-in antenna, and belongs to the technical field of antennas. (2) Background technology [0002] In the past few years, multifunctional integrated global wireless communication systems, wireless sensor networks and microwave imaging systems have made great progress. The evolution of wireless multi-mode operation requires a transition from designing single-band antennas to providing multiple single-band antennas in portable wireless devices. Due to the budgetary pressure on manufacturing cost per antenna, the rapid growth of multi-mode mixed-signal chips, and the reduction in the space allocated for antennas in portable wireless systems, the traditional method of using multiple antennas on the same wireless device is gradually decreasing. The method of using multi-frequency antenna has simple geometric form and excellent radiation performance. The built-in antenna also conforms ...
