RESEARCH ON ANTENNAS. PART 1. ROD ANTENNAS WITH INTEGRATED TUNNEL DIODE. PART 2. SCIMITAR ANTENNAS

Abstract

Part I. Rod antennas with integrated tunnel diodes. A rod is cut in 2 parts and joined again by a complex impedance. This impedance is produced by a tunnel diode, shunted by a short circuited line of variable length. Current distribution and input impedance are calculated and measured. Amplification factor and mutual coupling between 2 parallel antennas are treated theoretically. A method for measuring the mutual coupling is developed. Part II. Scimitar antennas. For better understanding the radiation diagram, the electrical and magnetical near field and the current distribution on the scimitar is measured. To improve the broadband matching of the input impedance and the radiation diagrams new forms of scimitars were tested (radiation diagram, input impedance, near field and current distribution).
