Abstract

Embodiments of the invention provide an ultra-wide-band planar monopole antenna array, a communication device and terminal equipment. The ultra-wide-band planar monopole antenna array comprises a dielectric substrate, a first grounding plate, a second grounding plate, a neutral line, a radiation patch and a microstrip feeder line of a first planar monopole antenna, and a radiation patch and a microstrip feeder line of a second planar monopole antenna, wherein the first grounding plate and the second grounding plate are symmetrically printed on the lower surface of the dielectric substrate along a center line of the dielectric substrate respectively; the radiation patch and the microstrip feeder line of the first planar monopole antenna, and the radiation patch and the microstrip feeder line of the second planar monopole antenna are symmetrically printed on the upper surface of the dielectric substrate along the center line of the dielectric substrate respectively; and the two ends of the neutral line are connected with the radiation patch of the first planar monopole antenna and the radiation patch of the second planar monopole antenna respectively. By loading the neutral line on the antenna array, the antenna array can be decoupled, thereby greatly strengthening the isolation degree between antenna array elements; and in addition, the ultra-wide-band planar monopole antenna array is simple and convenient to implement.

Description
