ABSTRACT:
An electromagnetic horn antenna (100). The antenna can include a horn housing having a throat portion (102), a tapered portion (106, 104) and an aperture108. At least one cavity structure (142, 144, 138) can be provided within the horn housing. The cavity structure can include at least one wall (138) formed of a dielectric material. A conductive fluid (136) and a fluid control system (103) can be provided. The fluid control system can control a volume and a position of the conductive fluid contained within the cavity structures for dynamically modifying at least one electrical characteristic of the electromagnetic horn antenna.
