Spiral Antenna Cuts Low Profile To 9.4 GHz (.PDF)

    Feb. 12, 2016
    This novel, miniature Archimedean spiral antenna achieves a low input impedance through the use of a tightly controlled exponentially tapered spiral line for implementing the impedance conversion. 

    Archimedean spiral antennas (ARSAs) are attractive for a variety of RF and microwave applications...
