    摘要: A phase delay line (110). The phase delay line can include an RF transmission line (111) and a fluid channel (109) having a serpentine configuration. The transmission line can be coupled to a solid dielectric substrate material (102), for example a substrate formed from a low temperature co-fired ceramic material. The fluid channel can be coupled to the RF transmission line along at least a portion of a length of the transmission line. A phase delay of the RF transmission line can be selectively varied by adjusting a distribution of the fluidic dielectric (130) present within the fluid channel. Similarly, the phase delay of the RF transmission line also can be maintained constant as an operational frequency of the RF transmission line is varied.

    摘要: An antenna can comprise a conductive reflecting surface (204) and a plurality of cells (202) disposed over the conductive reflecting surface. The plurality of cells can be formed from a solid dielectric material such as a low temperature cofired ceramic. Each cell can define a cavity for containing at least a fluid dielectric (406). One or more fluid processors (404, 424) independently vary a volume of the first fluid dielectric in the plurality of cells for producing a redirected RF beam at a selected angle relative to an incident RF signal impinging on the conductive reflecting surface.

    摘要: 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).
