Antenna system of handheld equipment capable of intelligent switching and switching method

Abstract

The invention discloses an antenna system of handheld equipment capable of intelligent switching and a switching method. The antenna system comprises a main antenna, a first MIMO antenna and a second MIMO antenna, wherein the main antenna is arranged at the bottom of the handheld equipment and used for the emitting and the main receiving of a plurality of frequency band signals, the first MIMO antenna is used for the second path receiving of low frequency band signals, the second MIMO antenna is arranged at the bottom of the handheld equipment and used for the second path receiving of high frequency band signals, and a double-pole double-throw switch used for cross switching is arranged between the second MIMO antenna and the main antenna. The antenna system of handheld equipment capable of intelligently switching and the switching method split a traditional full frequency band MIMO antenna into the first MIMO antenna and the second MIMO antenna, the first MIMO antenna is arranged at the top of the handheld equipment, the second MIMO antenna is arranged at the bottom of the handheld equipment, and the second MIMO antenna can be intelligently switched with an original main antenna at the bottom of the handheld equipment. Through the antenna system of handheld equipment capable of intelligently switching and the switching method, the design difficulty of the antenna can be reduced, the high frequency band emitting performance of a mobile is improved, and the problem that when the high frequency band coverage is poor, the uplink capacity is insufficient in handheld state is solved.

Description

technical field [0001] The invention relates to the field of antenna systems for handheld electronic equipment, in particular to an antenna system and a switching method for intelligently switchable handheld equipment. Background technique [0002] At present, handheld electronic devices such as mobile phones integrate more and more functional modules, while mobile phones are becoming thinner and thinner. At the same time, with the popularization of 4G LTE networks, smart phones need to support more and more frequency bands. Antenna design presents great challenges. The 4G LTE network uses a large number of high-frequency bands, such as domestic TD-LTE Band 38 / 39 / 40 / 41 and LTE FDD Band 1 / 3, which are all high-frequency bands higher than 1700MHz. The high-frequency band itself has poor coverage, especially indoors. , the signal will be relatively poor, and when the user browses the web or makes a phone call, the signal will be even worse due to the impact of the hands on the...
