Abstract

The invention provides a diversity antenna device and a terminal. The device comprises a processor, a transceiver and an antenna body and also comprises a switch module, wherein the processor is connected to the transceiver, the antenna body is connected to the transceiver by the switch module and a radio-frequency transmission line, the antenna body comprises N antenna oscillators, N is an integer larger than 2, the switch module comprises two input ends and N output ends, the two input ends are connected to the transceiver, the N output ends are respectively connected to the N antenna oscillators, the switch module is used for selectively making two of the N output ends in communication states, and the other output ends outside the two output ends are in disconnection states. With the device provided by the scheme, more diversity parameters can be obtained by a few antenna oscillators, the limitation on the volume of the terminal can be reduced by reducing the antenna volume on the premise that the diversity parameter can be met, and the device can be favorably and greatly applied to a product.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a diversity antenna device and a terminal. Background technique [0002] With the vigorous development of wireless technology, the application field of wireless network is constantly increasing, making the application of wireless terminal equipment one of the important indoor high-speed wireless data access means, with huge application potential. The application of MIMO (Multiple-input and Multiple-output) technology and diversity technology also makes the wireless link rate higher and higher. However, MIMO technology and diversity technology require the isolation between antennas and the increase in the number of antennas will increase the terminal The size of the equipment, which is contrary to the development trend of terminal equipment miniaturization. [0003] refer to figure 1 , figure 1 It is a common dipole antenna in the prior art. The antenna body is composed of two...
