Re: NEC-LIST:helical antennas

Good day all.

Earlier I referred to a paper by Dirk E Baker on broadband matching of
helical antennas. The reference is:

[1] Dirk E Baker, "Design of a broadband impedance matching section
for peripherally fed helical antennas," Allerton Antenna Applications
Symposium, U of Illinois, 1980.

For quadrifilar helix antennas for GPS use there is also the paper by:

[2] Samuel JP Laube, "GPS antenna designs," Joint UniversityProgram
for Air Transportation Research - 1984, NASA Conference Publication
2452, Langley Research Center, Virginia, Jan. 18, 1985.

Laube cites the Kilgus paper:

[3] CC Kilgus, "Resonant quadrifilar helix design," Microwave
Journal, pp. 49-54, December 1970.

I trust this will be of use to some of you.

Best regards,
Duncan Baker.
