Abstract
The concept of prompt aperture efficiency is introduced for impulse radiating antennas (IRA's) and the efficiency is analyzed in detail for a specific class of lens IRA's. By using two isorefractive media, one with a low impedance within the aperture of the IRA and one with a high impedance outside the aperture, the power on the TEM transmission linefeed structure of the IRA can be concentrated within the aperture, thereby improving the prompt aperture efficiency beyond what is possible using a single medium.
