Abstract

The invention provides a printing boardband terminal antenna with smaller occupying space. The printing boardband terminal antenna comprises a first bent metal strip group and a second bent metal strip group; a gap is formed between the first bent metal strip group and the second bent metal strip group; a microstrip feed line is used for directly feeding electricity to the first bent metal strip group so as to excite a high-frequency current on the first bent metal strip group to form resonance; and a high-frequency current on the second bent metal strip group is excited by capacitive coupling of the gap between the first bent metal strip group and the second bent metal strip group to form resonance. According to the invention, the first bent metal strip group and the second bent metal strip group are not directly connected, a plurality of frequency points are matched according to the distributed parameter effect of the gap between the two metal strip groups, and therefore the bandwidth can be widened in a larger extent. Therefore, the size occupied by the antenna can be reduced; in addition, a dedicated matching circuit and a special substrate material are not required in the invention.

Description

technical field

[0001] The invention belongs to the technical field of antennas, and in particular relates to a broadband terminal antenna. Background technique

[0002] At present, the development of mobile communication technology has made the sense of space distance between us smaller and smaller. With the use of relatively small electronic technology products, we can exchange information with each other at any time, which is inseparable from the use of antennas. At the same time, with the development of personal communication services, people's requirements for wireless products are becoming more and more stringent, which is mainly reflected in two aspects: broadband and miniaturization. In particular, the development of high-speed data transmission systems and military broadband wireless systems requires antennas to have wider bandwidths. In view of this, in order to improve the working performance and working efficiency of wireless communication receiving and sending ...
