Abstract
The invention concerns a multi-mode electromagnetic horn antenna that can operate over two or more distinct bands of frequencies. The horn (100) includes a throat portion (102) and an aperture (108) disposed at an end of the horn (100) opposed to the throat portion (102). A flared section (104, 106) is disposed between the throat portion and the aperture. At least one dimension of the flared section can increase in size along an axial length of the horn defined between the throat portion (102) and the aperture (108). Further, a dielectric load (103) can be disposed within the throat portion (102). The dielectric load is advantageously comprised a fluid dielectric (103).
