Abstract

The invention provides a miniaturized inverted-E-shaped groove type ultra wide band millimeter wave microstrip antenna. The antenna comprises a square medium substrate (1), a grounding surface (2) disposed at one side of the square medium substrate, a radiation patch (3) disposed at the other side of the square medium substrate, and a feed line (7). The antenna is characterized in that the outer contour of the radiation patch is rectangular-shaped, the radiation patch is provided with an inverted-E-shaped groove (4) and two fillet rectangular-shaped grooves (5), and the two fillet rectangular-shaped grooves are disposed below the inverted-E-shaped groove. The antenna has the advantages of good radiation features, high gain, small dimension, low profile, easy conformation, easy integration, simple processing, low cost and the like, thereby being quite suitable for 5G mobile communication large-scale networking.

Description

technical field [0001] The invention relates to an antenna used in a mobile communication system. Background technique [0002] At present, 4G mobile communication technology has been successfully commercialized, and people can enjoy faster data transmission speed and better call quality. With the progress and development of the times, mobile life gradually occupies a dominant position in people's lives. In addition, the rise of the Internet of Things and the concept of VR makes the interaction of characters and the connection of things in the future a development trend, and its demand for information will rise sharply. A more efficient, low-latency, and secure mobile communication network is required. However, the current mobile communication technology is facing problems such as the shortage of spectrum resources and limited system capacity, which is far from meeting the needs of future mobile Internet. Therefore, the development of the fifth generation (5G) mobile commu...
