ABSTRACT:
A circularly polarized microstrip line antenna for receiving or transmitting a signal of a particular wavelength includes a dielectric substrate having a ground plate provided on one surface thereof and having a microstrip line formed on another surface thereof. The microstrip line has an omega shaped fundamental portion composed of a loop portion and a pair of straight portions. The loop portion is one of either a regular polygon or a continuous closed curve having a length equal to the particular wavelength. The loop portion is symmetric about an axis which is on one of the surfaces of the substrate and is at right angles to the straight portions of the microstrip line.
