Broadbanding of Electrically Small HF Antennas for Frequency Agile Applications by Use of PIN Diode Switched Matching Networks
J. Neal, Daniel J. Miley · 1983
The need for and capabilities of HF frequency agile antenna systems are presented. Since frequency agile communications are employed on electrically small platforms, the antennas are necessarily small and narrowband. The antenna must be made to appear broadband by the use of a frequency hopping antenna matching network. State-of-the-art design requirements and performance levels for frequency hopping antenna matching networks are presented.
