Abstract

The present invention discloses a multi-band printed antenna, which includes: a ground plane; and an antenna part, including a short-circuit arm electrically connected to the ground plane, a folding arm connected to the short-circuit arm, and a feed connected to the folding arm. The feed arm is used to send signals into the folding arm and the short-circuit arm; wherein the folding arm has at least one bending point, and according to the bending point and the total length of the folding arm, at least two resonant frequencies are provided .

Description

technical field [0001] The invention relates to a multi-band printed antenna. Background technique [0002] Existing printed antennas can only operate at a single frequency, and are not suitable for multi-band communication systems such as WLAN802.11a / b / g. [0003] Therefore, the present invention provides a printed antenna capable of operating at multiple frequencies, especially a multi-band printed antenna with coupling effect. Contents of the invention [0004] The purpose of the present invention is to provide a multi-band printed antenna to solve the above problems. [0005] According to the above purpose, in terms of one of the viewpoints, the present invention provides a multi-band printed antenna, comprising: a ground plane; and an antenna part, including a shorting arm electrically connected to the ground plane, and a The folding arm, and the feeding arm connected with the folding arm, the feeding arm is used to send the signal into the folding arm and the short...
