Description

Technical Field

[0001] The utility model relates to the technical field of WiFi6E antennas, specifically to a WiFi6E antenna with an HDMI interface. Background Art

[0002] With the progress of society and the development of science and technology, people have more and more demands on the appearance and texture of electronic equipment, signal reception and transmission, and the requirements for transmission rate and stability are also getting higher and higher. Moreover, with the development of technology, in order to adapt to global use, the frequency band requirements of antennas will become more and more comprehensive. This will require the frequency band of antennas to be wider and wider. As a result, WIFI 6E antennas appeared in addition to WIFI antennas. WIFI 6E antennas can use wide frequency bands. Generally, the frequency band of WIFI antennas is 2400~2500MHz&5100~5850MHz, but with the advancement of communication technology, the frequency band of antennas has increased to 2400~2500MHz&5100~5850MHz&5925~7125MHz, so wide-bandwidth WIFI 6E antennas have appeared, which can meet the high-speed transmission of signals and increase the transmission stability of antennas.

[0003] With the development of wireless communication, more and more electronic devices are equipped with antennas. Antennas are an indispensable part of electronic devices, especially mobile Internet devices such as smart phones, tablet computers, and laptops.

[0004] Due to the requirement of portability, slimming and light weight have become the development trend of electronic devices. The ultra-thin body makes the hardware built-in space of electronic devices quite limited, leaving less and less space for antennas. The electronic components in the body are highly integrated, and the volume of the antenna is too large relative to the body. In addition, the HDMI interface and antenna of existing devices are independently set, which takes up a lot of space and cannot meet the demand for thin and light electronic products. Summary of the invention

[0005] In response to the above problems, the utility model provides a WiFi6E antenna with an HDMI interface, which integrates the HDMI interface and the WiFi6E antenna into a group of composite antennas. The overall volume is small, which saves subsequent installation space and ensures the lightness and thinness of the electronic device.
