ABSTRACT

This paper presents an extremely wideband array antenna with orthogonal arrangement and parallel feeding by smoothed round wires for circular polarization. In conventional studies, the bandwidth of circular polarization and flat impedance was limited only as a few per cent of the central frequency. This paper present first that a novel unit antenna is composed of feed, reactance, and ground elements to realize wideband and lee spurious resonances. This paper present secondly that the array is composed of four antennas arranged in orthogonal and fed in parallel with phase delay of 90 degrees for circular polarization. Based on computer simulation, it was first found that enough wide bandwidth obtained for circular polarization. And it was also found that the flat impedance bandwidth is extremely wide, it was concluded that this configuration first realized to compose a practical array antenna with multiple unit antenna.
