Title:
MICROSTRIP DUAL-POLARIZED ANTENNA FOR WIRELESS TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/037656
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a microstrip dual-polarized antenna for wireless transmission. The antenna comprises: a first dielectric substrate; a metal radiation sheet disposed on the first dielectric substrate, the metal radiation sheet defining a first square, each side of the first square defining a respective concave notch; a second dielectric substrate; a metal ground sheet disposed on the second dielectric substrate, the metal ground sheet defining a second square, the metal ground sheet defining four open slots, each of the open slots respectively dividing each corresponding right angle of the second square into two oblique angles; and at least one pillar respectively coupled to the first dielectric substrate and the second dielectric substrate, so that the first dielectric substrate and the metal ground sheet are separated by an air gap.
