Title:
MICROSTRIP ANTENNA AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/040765
Kind Code:
A1
Abstract:
The present application provides a microstrip antenna and a communication device. A first radiation patch is arranged on the side of a first microwave dielectric substrate furthest from a second microwave dielectric substrate; a second radiation patch is arranged on the side of the second microwave dielectric substrate closest to the first microwave dielectric substrate; a gap layer is disposed on the side of a third microwave dielectric substrate closest to the second microwave dielectric substrate; and a feed microstrip line is arranged on the side of the third microwave dielectric substrate furthest from the second microwave dielectric substrate. The first radiation patch and the second radiation patch are of a first form or of a second form, so as to construct a spatial filter. The gap layer has etched therein two orthogonal and symmetrical gaps, and a tail end coupling segment of one feed microstrip line perpendicularly crosses a gap in a gap layer. Constructing a spatial filter from the first radiation patch and second radiation patch in the microstrip antenna results in no longer needing to separately introduce a filtering structure, avoiding loss resulting from the introduction of the filtering structure, and ensuring the gain performance of the antenna.
