摘要： A microwave element having a frequency selective surface (FSS) is formed of a substantially planar substrate of dielectric material which is transparent to electromagnetic radiation, and supports an array of radiators wherein the radiators are arranged in a plurality of sets of radiators. In each set of radiators, in a preferred embodiment, there are three concentric radiators fabricated of an electrically conductive material. The outermost radiator has a hexagonal closed form, and the inner radiators are configured as circular annuluses. In each set, the largest radiator has a circumference equal to a wavelength of a first frequency of radiation to be reflected from the (FSS), the sets being spaced apart by a spacing equal to one-third of the foregoing wavelength in the dielectric substrate. In a two-dimensional array of the sets of the radiators, the sets are located at vertices of equilateral triangles. An antenna incorporating the FSS includes a first horn operative at radiation of the foregoing wavelength and a reflector, both of which are disposed on one side of the FSS. Additional horns operative at higher frequencies located on the opposite side of the FSS for transmittal of radiation through the FSS.

摘要： An antenna has one feed for an S-band electromagnetic signal, and a second feed constructed as an array of radiators to service two C-band signal channels. A subreflector having a microwave frequency selective surface (FSS) is placed in front of a main reflector. The C-band feed is constructed of an array of square aperture horns joined by separate transmit and receive barline beam-forming networks, and a meanderline polarizer to produce circularly polarized radiation patterns. Tapered ridges extend longitudinally along inner wall surfaces of each of the horns to provide increased bandwidth to the C-band feed. The frequency selective surface is constructed, typically, of a generally planar substrate of material transparent to electromagnetic radiation, and numerous metallic, generally annular, radiating elements, or resonators, arranged on the substrate in an array of repeating nested sets of the radiating elements. The lower frequency S-band feed is located behind and to the side of the subreflector for transmission of radiation via a folded optical path to the main reflector. The C-band feed is located in front of and to the side of the subreflector for transmission of radiation along a straight path through the FSS to the main reflector. The locating of the two feeds to the side of the subreflector permits the subreflector to be stowed by folding down upon the C-band feed, and the main reflector to be stowed by folding down upon both the S-band feed and the stowed subreflector.

摘要： An antenna system having a front reflector and a rear reflector arranged in tandem, a front feed for illuminating the front reflector, and a rear feed for illuminating the rear reflector. Each of the reflectors has a generally dish-shaped configuration, and the feeds are located in positions offset from axes of the respective reflectors. The front reflector is reflective to a first radiation, while being substantially transparent to a second radiation except for a fraction of the power of the second radiation. The fractional part of the second radiation is reflected from the first reflector as an interfering beam, the interfering beam being scanned away from a coverage region of a beam of the first radiation by an offset between the feeds. The radiations may differ in polarization or in frequency. There may be a complete shading of the rear reflector by the front reflector from the radiation of the rear feed to produce uniform illumination of the rear reflector for greater accuracy in a formation of a beam from the rear reflector. Six degrees of freedom in positioning and orientation of the reflectors and their feeds provides maximum design flexibility for obtaining a compact antenna.
