Problems solved by technology

Electromagnetic signals are sent and received through the antenna. Due to the disadvantages of large size and easy damage of the external antenna, more and more electronic devices use built-in antennas.
With the development of wireless communication devices, traditional built-in single-frequency antenna devices can no longer meet people's needs for wireless communication. In order to meet the multi-band communication capabilities, it is usually hoped that the system will integrate mult...

Abstract

The invention relates to a square three-frequency antenna device and communication equipment. The device comprises a dielectric layer, a radiation part, a grounding part, and an excitation part, wherein the radiation part is arranged on the upper surface of the dielectric layer, and the grounding part is arranged on the lower surface of the dielectric layer; the excitation part is used for connecting the radiation part with the grounding part to form a current loop; the radiation part comprises a first rectangular resonance body and a second rectangular resonance body which are perpendicular to each other; and the grounding part comprises a first rectangular metal patch and a second rectangular metal patch which are perpendicular to each other. The square three-frequency antenna device isa built-in onboard antenna with three frequency bands, the antenna device utilizes the square and annular structures and the vertical rectangular resonators to realize coverage of multiple frequency bands, and the antenna device is high in gain, small in occupied size, relatively high in bandwidth, easy to manufacture and capable of radiating backwards, so energy efficiency of the antenna device is improved on the whole.

Description

technical field [0001] The invention relates to the technical field of communication components, in particular to a square tri-frequency antenna device and communication equipment. Background technique [0002] With the rapid development of wireless communication technology and the increasingly widespread application of radio equipment, antennas, as equipment for receiving and transmitting radio waves, are a key component in wireless communication systems. Electromagnetic signals are sent and received through antennas. Due to the disadvantages of large size and easy damage of external antennas, more and more electronic devices use built-in antennas. With the development of wireless communication devices, traditional built-in single-frequency antenna devices can no longer meet people's needs for wireless communication. In order to meet the multi-band communication capabilities, it is usually hoped that the system will integrate multiple antennas or use a single broadband ante...
