Slot spiral antenna with integrated balun and feed

requirements of the low proflle spiral antenna geometry. A spiral antenna with integrated parallel-plane feeding structure is proposed in this paper. The antenna used has obviously improved axial ratio compared to the equiangular spiral antenna at low frequencies. And the traditional balun in the third dimension is moved to the planar plane.

Simons Sverdrup Technology, Inc. Lewis Research Center Group Brook Park, Ohio Richard Q. Lee National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio and Thomas D. Perl University of Akron Akron, Ohio Prepared for the IEEE-APS ... Basic Antenna Theory - Wireless – The slot length is some (λ/2) for the slot antenna and (λ/4) long for the INF antenna. • The INF and the slot antennas behave similarly. • The slot antenna can be considered as a loaded version of the INF antenna. The load is a quarter-wavelength stub, i.e. a narrowband device. • When the feed point is moved to the short-circuited ... The Infinite Balun - Antenna Theory

solution for antenna systems using spiral antennas. The infinite balun used in many papers for spiral (slot) antennas basically consists of a coaxial cable spiraled along the antenna arms with the coaxial shield soldered to the antenna arm. At the center, the coaxial pin connects to the other antenna arm. This balun construction only provides ... High-power ultra-wideband spiral antenna arrays - IEEE ...
