Title:
APPARATUS AND METHOD FOR A HIGH APERTURE EFFICIENCY BROADBAND ANTENNA ELEMENT WITH STABLE GAIN
Document Type and Number:
WIPO Patent Application WO/2016/155391
Kind Code:
A1
Abstract:
Embodiments are provided for an antenna element design with high aperture efficiency and stable gain across a frequency range. In an embodiment, the antenna element is obtained by placing a conductive layer(450) on a dielectric substrate(401), forming a slot(430) in the conductive layer(450), and forming two feed lines(440) inside the dielectric substrate(401). A dielectric layer(402) is placed on the dielectric substrate(401) and over the conductive layer(450) and the slot(430). A circular or elliptical conductive wall(412) is formed inside the dielectric layer(402). A conductive element(410) is also formed on the dielectric layer(402) and over the slot(430). One or more second dielectric layers(403) are placed on the dielectric layer(402) and over the conductive element(410). A second circular or elliptical conductive wall(412) is formed inside each second dielectric layer(403). A second conductive element(420) is also formed on each second dielectric layer(403), over the conductive element(410).
