Abstract

High power microwave (HPM) sources are typically bulky and massive in order to be able to radiate the extremely high source powers with a good impedance match and low losses. For this reason, it is sometimes difficult to incorporate an HPM antenna onto a desired platform when the available space is small. In previous work, we have adapted an electrically small EZ antenna to operate with a mesoband, quarter-wave oscillator source. The EZ antenna operates over a ground plane, but is conformal and low profile in that the electrical size is on the order of λ /12, making it attractive for applications where there is sufficient internal space to place a full source, but only limited space outside the platform for the radiating subsystem. Here we extend the capabilities of the oscillator/EZ antenna combination by introducing a dual band design for the antenna and altering the oscillator to produce multiple resonant frequencies. Designs are shown here that operate in the UHF (500-800 MHz) and L-band (1.5-1.8 GHz), but the operation frequencies are essentially arbitrary. This paper shows modeling results that predict high antenna efficiency with electrical sizes of ka < 1 at f = 500 MHz.
