Two-arm Archimedean Spiral Helical Antenna with Wraparound Absorber

Two-arm spiral antennas usually have wideband characteristics (these antennas usually have constant beam width and circular polarization over a broad range of frequencies), 1,2 and thus are suitable for communicating (transmitting and receiving) over bands of frequencies (multiple channels). At lower frequencies, for a given size, these antennas tend...
