Abstract

PURPOSE:To establish the antenna producing the circular polarized wave without deterioration of performance and with simple construction, by selecting the slope of the straight line slot shaped on the side wall of rectangular waveguide and the position. CONSTITUTION:At the side wall of the rectangular waveguide 2 having the power feeding section 1, the slots 5, 6 narrow and with a slope of 45 deg. and -45 deg. to the tube axis taking the two points A, B in the distance of 1/4 wave length in-tube wave length as the center are provided. The emitted electric field from the slots 5, 6 like these is almost equal to the direction vertical to the side wall and has the phase difference of 90 deg., allowing to obtain the circular polarized wave as the synthesized electromagnetic waves. Futher, by locating a plurality of antennas 10 having the phase shifter 30 and termination resistance 20 and different in the slot position by 1/2 wave length alternately, the planer array antenna can be constituted.
