Abstract :
In this paper, we have presented the transmitter, antenna array, transmission and evaluation of the circularly polarized ultra-wideband signal at boresight direction. From measurements, it has been shown that, in the frequency band of 2.6-5.5 GHz, the transmitted signal has axial ratio of < 1 dB, polarization tilt between plusmn30deg, and left-hand polarization sense.
