Abstract

The embodiments of the invention provide an ultra-wide plane monopole antenna array, a communication device and a terminal device. The antenna array includes a medium substrate, a neutralizing wire, and a first earth plate and a second earth plate which are symmetrically printed on a lower surface of the medium substrate along a first central line of the medium substrate, and a radiation patch and a microstrip feeder of a first plane monopole antenna and a radiation patch and a microstrip feeder of a second plane monopole antenna which are symmetrically printed on an upper surface of the medium substrate along the first central line of the medium substrate; specified edges of the first earth plate and the second earth plate have symmetrical recessed parts, a specified edge being an edge approaching the first central line of the medium substrate, the symmetrical recessed parts being symmetrical around a second central line of the medium substrate, and the second central line being perpendicular to the first central line; two ends of the neutralizing wire are respectively connected to the radiation patch of the first plane monopole antenna and the radiation patch of the second plane monopole antenna. The loading of the neutralizing wire on the antenna array greatly intensifies isolation level among antenna array elements.

Description

【Technical field】 [0001] The invention relates to the technical field of communication, in particular to an ultra-wideband planar monopole antenna array, a communication device and a terminal device. 【Background technique】 [0002] Modern wireless communication systems require higher data transmission rates, greater channel capacity and wider communication frequency bands. Ultra Wideband (UWB) technology is widely used in various wireless devices due to its unique characteristics. The expanded bandwidth realizes high data rate transmission, and the inherent robustness of multipath propagation ensures high reliability. sex. [0003] With the increasing application of UWB technology in Multiple-Input Multiple-Output (MIMO) antenna systems, UWB MIMO antennas have attracted great attention in both academic and industrial fields. Ultra-wideband and high isolation are the primary goals of UWB MIMO antenna systems. In the prior art, different technologies are used to implement UW...
