Power-Handling Capability of ECM Antennas.

Abstract : The electrical breakdown characteristics of the LPJ-1 and the SLOT L-1 antennas furnished by Lincoln Laboratory were measured. Modifications to increase the power-handling capability of the SLOT L-1 antenna were suggested. The effect of laser irradiation on antenna breakdown was investigated using ruby and CO2 lasers. The antenna studied was a dielectric plugged X-band waveguide. Blackout times and altitudes were estimated for the TBV vehicle C-band beacon and S-band telemetry antennas. (Author)
