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 ...

Fig.1: Front View of Antenna In the present paper, an elliptical microstrip patch antenna for Ultra Wide Band applications has been designed. We are using elliptical patch because it provides comparatively larger bandwidth than others. Fig.2: Bottom View of Antenna The partial ground plane method is used in this antenna,

Radial microstrip slotline feed network for circular ... Abstract In mobile and satellite communications there is a need for low cost and low profile antennas which have a toroidal pattern. Antennas that have been developed for mobile communications include a L-Band electronically steered stripline phased array, a Ka-Band mechanically steered elliptical reflector antenna and a Ka-Band printed dipole.
