  • Abstract
    This article analyses a novel 4-arm spiral antenna operating in the 2nd mode. The CST MICROWAVE STUDIOreg (CST MWS) is extensively used to study effects of various antenna parameters. Good performance over four octave bandwidth is achieved in terms of angular phase linearity, axial ratio, and wobble on wave (WoW). The total cumulative phase is 720 degrees for mode 2 pattern at the assigned elevation. Phase linearity over the entire bandwidth is well maintained. The standard deviation of phase is controlled within design requirement.
