Abstract

An antenna and an MIMO antenna system are described. At least one antenna secured to a housing of a device. The antenna has a size of 1 / 4 wavelength of a central frequency of the antenna and body, theground pad and the feed pad of the antenna have an impedance matching an RF communications circuit. A plurality of the antennas may be arranged in the housing to form a MIMO antenna system.

Description

[0001] cross application [0002] This application claims priority from prior application to U.S. Patent Application Serial No. 15 / 494,048, filed April 21, 2017, entitled "A Wideband MIMO Antenna System for Electronic Devices," the entire contents of which are incorporated by reference incorporated into this text. technical field [0003] The present invention relates to an antenna, in particular to a broadband antenna and the arrangement of the antenna system in electronic equipment. Background technique [0004] Modern electronic devices such as smartphones are integrating more and more functions and technologies. Sometimes, it may be necessary to add additional hardware to an electronic device in order to provide new functionality. For example, in modern electronic devices, antennas need to be added to support 5G technology. [0005] In a conventional mobile or wireless electronic device, the antenna may be printed on a printed circuit board (Printed Circuit Board, PCB...
