Abstract
Official abstract text for this publication.
A radial line slot array antenna has a slotted conductor plate in which a plurality of slots are formed and arranged in a spiral. The plurality of slots are arranged in the slotted conductor plate such that the arrangement distance in a radial direction between the slots varies gradually between a first portion determined based on a first frequency and a second portion determined based on a second frequency that is different from the first frequency.
