SPIRAL ANTENNA WITH TILTED RADIATION PATTERN

摘要

A spiral antenna with a tilted radiation pattern is disclosed. The disclosed antenna includes a dielectric substrate; a spiral radiation body which is formed on the upper part of the dielectric substrate; a ground surface which is formed in the lower part of the dielectric substrate; and a slot which is formed in a region of the ground surface, and has an oval shape. The disclosed spiral antenna can provide a tilted beam pattern.
