Abstract

PURPOSE:To enable to transmit and receive the circular polarized wave, by giving the phase difference of 90 deg. to the electric field of the slot constituting one set of element antenna and making orthogonal each other, among a plurality of slots arranged along a pair of feeding strip line. CONSTITUTION:The feeding strip lines 13A and 13B are constituted by coating a pair of band strip conductors 12A and 12B parallelly on one surface of the dielectric substrate 11, and the ground conductor film 14 is coated on the entire surface of other plane. Next, in the conductor film 14, two slots A and B tilted by 45 deg. to the vertical direction of the lines 13A and 13B and having the length of a half wave electromagnetically coupled with the lines are formed along the line. After that, one end of the lines 13A and 13B is respectively connected to the high frequency power supply 15A and 15B placed apart from the distance of ls and ls, from the feeding points FA and FB of the slots A and B, and another end is respectively connected to the termination impedances 16A and 16B of ZT and ZT, apart from lT and lT, from FA and FB.
