Abstract

The invention provides a short-circuit coplanar waveguide feed-in dual-polarized broadband antenna, and the antenna comprises a printed circuit board which is provided with a first surface and a second surface; the first surface of the printed circuit board is provided with a signal line, the second surface of the printed circuit board is provided with a grounding surface, and the printed circuit board is internally provided with a conduction body so as to enable the signal line to be electrically connected with the grounding surface. The ground plane surrounds the signal line to form a coplanar waveguide feed-in monopole antenna and has the characteristics of a bipolar antenna, so that a multi-frequency and broadband dual-polarization efficiency antenna is created. And a simple architecture is used to form an array antenna with a wide operating frequency band.

Description

technical field [0001] The invention provides a short-circuit coplanar waveguide feeding dual-polarization broadband antenna, especially a dual-polarization efficiency antenna for creating multi-frequency and broadband. And, a simple structure is used to form an array antenna with a wide operating frequency band. Background technique [0002] Wireless communication technology occupies an indispensable part in the convenient life of today's society. With the comprehensive deployment of wired and wireless local area networks, mobile electronic devices (Mobile Devices) must also be equipped with wireless antennas for signal reception and transmission. The mobile electronic device can use the Internet and transmit data through the wireless local area network. [0003] The above-mentioned wireless antenna of the mobile electronic device usually belongs to a single body or is integrated with other antennas with different functions, and its volume is usually too large to affect th...
