Abstract

The invention discloses a low-profile broadband tri-polarized antenna for human body local area network communication. The antenna is composed of a patch antenna structure loaded with a metal short-circuit pin ring array and a double-layer E-shaped patch antenna structure, the radius of the antenna is 0.58[lambda]0, the total thickness of the antenna is 0.09[lambda]0, [lambda]0 is the free space wavelength of the antenna at 5GHz, and the profile of the antenna is very low. The antenna comprises a patch antenna structure (1) loaded with a metal short-circuit pin ring array and a double-layer E-shaped patch antenna structure (2), wherein the double-layer E-shaped patch antenna structure (2) is located right above the patch antenna structure (1) loaded with the metal short-circuit pin ring array, and the double-layer E-shaped patch antenna structure (2) and the patch antenna structure (1) are arranged in parallel and are separated by an air layer. By using the structure of the invention,a tri-polarized miniature antenna with low profile and wide frequency band can be realized, and the antenna has a wide application prospect in the aspects of multi-mode communication and multiple-input multiple-output communication of a human body local area network.

Description

technical field [0001] The invention belongs to the field of wireless communication system electronic devices, and in particular relates to a low-profile broadband triple-polarization antenna for human body local area network communication, which has multiple ports, and when each port is excited, it can generate independent polarized The radiation pattern can support three different communication modes at the same time in the working frequency band close to 14% of the bandwidth, and is suitable for multi-mode broadband wearable communication systems, broadband multiple-input multiple-output communication systems and other fields. Background technique [0002] The continuous development of wireless communication technology and the rapid evolution of highly integrated electronic equipment have promoted the diversity of information acquisition means and information interaction, and devices working in the human body area network (body area network) have emerged as the times requi...
