T-shaped slot dual-band button antenna

Abstract

The invention relates to wireless communication equipment, and particularly relates to a T-shaped slot dual-band button antenna comprising a rectangular metal sheet, a ground plate and a coaxial hollow metal column which connects the rectangular metal sheet and the ground plate. The ground plate is a thin metal layer covered by fabrics. The rectangular metal sheet and the ground plate are respectively connected with the internal core and the external core of the coaxial hollow metal column for feeding. A shorting pin is also arranged between the rectangular metal sheet and the ground plate. A T-shaped slot is arranged on the rectangular metal sheet. The T-shaped slot is formed by a transverse rectangular slot and a longitudinal rectangular slot through vertical connection. Broadband, small size and low profile can be realized, and the antenna is small and convenient and great in concealing so as to replace the button in clothes and realize the function of wireless communication between all the equipment in a body center network without influencing the beauty of the clothes. Besides, the antenna is firm in structure and is not liable to deform so as to guarantee the stability of the antenna performance to a certain extent.

Description

technical field

[0001] The invention relates to a wireless communication device, in particular to a T-shaped slot double-frequency button antenna. Background technique

[0002] At present, wearable devices are in full swing. Some large communication product companies in the world have successively launched various wearable smart bracelets and smart watches. The concept of the body-centered network is the extension and development of the concept of wearable devices. The so-called body-centered network refers specifically to the body piconet worn on the human body and its access devices connected to the body-centered wireless network, wireless local area network or wired local area network. The key to the body-centered network is the control of electromagnetic radiation and the development of the human body antenna, and the human body antenna is the connection node of the body-centered network, and there are many challenges in its design. As we all know, antennas generally ha...
