Abstract

The present invention provides a wireless PIFA antenna, comprising a floor, a radiating unit, a feeding port and a short circuit, the radiating unit comprises a first radiating arm and a second radiating arm symmetrically arranged above the floor, and the first radiating arm and the second radiating arm The radiating arms form a quadrilateral with a diagonal notch, and are short-circuited at the notch, the feed port is located at the center of the notch on one side of the radiation unit, and the short circuit is included on both sides of the feed port The first short circuit and the second short circuit are arranged symmetrically, the first short circuit connects the first radiation arm and the floor, and the second short circuit connects the second radiation arm and the floor. The antenna is small in size, can be placed inside the product casing, and has good performance.

Description

technical field [0001] The invention mainly relates to the field of wireless communication, in particular to a wireless PIFA antenna. Background technique [0002] At present, the Internet of Things and people's lives are getting closer and closer. In the development of the Internet of Things, wireless communication technology has played an important role. As an important part of wireless communication, the antenna design is not only related to the performance of the product, but also affect the appearance of the product. The PIFA antenna generally uses a planar radiation unit as the radiator, and a large ground as the reflector. There are two pins close to each other on the radiator, which are used for grounding and feeding respectively. The traditional structure of the PIFA antenna generally has The following disadvantages: [0003] In order to ensure that the antenna has a good gain, the general structure of the PIFA antenna is large in size, which affects the appearanc...
