Abstract

The invention relates to a plane antenna which comprises a base plate, a feed line, a first radiating unit, a second radiating unit and a grounding unit, wherein the base plate is provided with an upper surface and a lower surface in parallel; the feed line is arranged on the upper surface; and the grounding unit is arranged on the lower surface and used for grounding. The plane antenna is characterized in that the feed line is divided into a long first feed section and a short second feed section by a feed point for feeding a signal, and the first feed section is longer than the second feed section by a half wavelength of the operation frequency of the plane antenna; and the first radiating unit and the second radiating unit are respectively two radiating metal sheets adjacent to the first feed section and the second feed section.

Description

technical field [0001] The present invention relates to an antenna, in particular to a planar antenna. Background technique [0002] The development of wireless communication networks has been evolving at a rapid pace. In the past, Wireless Local Area Network (WLAN) and Wi-Fi (Wireless Fidelity) provided regional wireless Internet access services. The limitations of the Internet cannot allow consumers to meet their needs for surfing the Internet anytime, anywhere. With the development of wireless communication, the whole network mobile and unlimited roaming applications are rising, and the demand for using handheld or mobile devices (such as mobile phones, PDAs, NBs, etc.) Therefore, World Interoperability for Microwave Access (hereinafter referred to as WiMAX) technology began to provide consumers with mobile communication services without regional restrictions, because this technology can transmit huge data over long distances and has a visual range In addition to the fe...
