摘要： A dielectric antenna of the present invention includes a pillar-shaped dielectric section for radiating an electromagnetic wave being fed thereto. The dielectric section includes a depressed portion in an upper portion thereof. The vertical cross section of the depressed portion has such a shape that the height of the dielectric section gradually increases toward the side surface of the dielectric section. For example, the depressed portion is a notch having a V-shaped vertical cross section. Alternatively, the depressed portion includes a flat surface portion.

摘要： An antenna having a high gain, of small-size, and capable of setting the radiation direction of electromagnetic waves in a desired direction. The antenna also allows electromagnetic waves to be radiated stably. The antenna has a first planar conductor shaped like a flat plate. Disposed on the first planar conductor is a bar-shaped dielectric strip having one end connected to a waveguide or a transmission circuit and the other end being an open end which does not reach the position of openings in a second covering planar conductor. The end surface of the open end of the dielectric strip is shaped like a flat surface, and a column-shaped dielectric resonator is disposed at the open end side on the extension axis of the dielectric strip. A surrounding member is provided around the side of the dielectric resonator so as to surround it with a space therebetween. Further, a second planar conductor is disposed so as to cover the top surfaces of the dielectric strip, the dielectric resonator and the surrounding member. The second planar conductor has two rectangular-shaped openings above the dielectric resonator so as to be parallel to the extension axis along the length direction of the dielectric strip and to a line symmetry of the strip.

摘要： An improved spherical gradient lens and a method of fabricating same. A uniform sphere of a material such as high density irradiated polystyrene or a methylpentene copolymer in the polyolefin family having a uniform relative dielectric constant is provided. A plurality of radially extending holes are formed therein, for example by drilling, the holes having a predetermined cross sectional geometry along axes extending radially from the center of the sphere. The geometry of holes is selected to control the resultant local density of material, and thus the relative dielectric constant as a function of distance from the center of the sphere. Hole diameters are chosen so as to be small compared to the shortest wavelength of interest with which the lens will be used.

摘要： The spherical dielectric lens with variable refractive index contains modules (1, 4, 7, 9, 12) connected with one another and made from homogeneous dielectric materials with various .di-elect cons. values, which are arranged in accordance with the given principle of change in dielectric permittivity .di-elect cons. from the radius value (r) of the lens, uniquely corresponding to the rule of variation of its refractive index (n). The modules (1, 4, 7, 9, 12) of the interior layers, which form the central cubic core, are inscribed in a sphere, are of cubic form and are equal in size, while the exterior modules (1, 4, 7, 9, 12) have an outer surface of spherical form, where the latter interior layer modules (1, 4, 7, 9, 12) fill out the central core up to the sphere. On at least two sides of each module (1, 4, 7, 9, 12) along its entire length are constructed a grooves which are broader to the inside (2, 5, 8, 10, 13, 16, 15) and/or protrusions (3, 11, 14) which have in pairs identical lateral cross-section, by means of which the modules (1, 4, 7, 9, 12) are connected with one another to form the spherical lens surface. Various combinations of construction of the grooves and protrusions on the sides of the module (1, 4, 7, 9, 12) are proposed.

摘要： A lens such as a Luneberg lens is used in a retro-reflector having a plurality of reflector elements formed in a mosaic covering a predetermined portion of the lens. Each of the reflector elements may be individually controlled independently of the others; in this way, an interrogation source whose direction can be determined can have its interrogation signals reflected back only to it by having only one or a selected few of the reflector elements act as reflectors. Reflection in other directions may be suppressed by causing the other mosaic elements to act as absorbers. In addition, the reflectors can have their reflective or transmissive properties modulated so as to act as amplitude or phase modulators of the interrogation signal. In this way, information can be imparted to the reflected interrogation signal. Doppler effects, on account of the velocity of a vehicle upon which the retro-reflector is mounted, are corrected for each of the individual reflector elements depending upon their positions on the Luneberg lens in relation to the vehicle and its direction of motion and velocity. The lens can be arranged with fixed elements in a pattern with symmetry about an axis of rotation of the lens; such elements need not be fixed, however, and may also be individually controlled or controlled as a group in a pattern.

摘要： The EHF omnidirectional antenna system (10) includes a shaped lens (12) that is illuminated by a corrugated horn (14). The lens is disposed in the far-field of the horn and has two shaped surfaces (20 and 30) which together disperse the beam from the horn, such that a nearly uniform coverage over hemispherical coverage area is achieved at a frequency of approximately 44 GHz. The method of making the lens utilizes a surface shaping analysis to develop the shaped surfaces of the lens. A surface matching layer (44) is applied to all surfaces of the lens to reduce surface reflection.

摘要： A multi-layered structure utilizes two impedance matching layers 4 and 6 and a base member 2 to provide an optimal transmission characteristic for double impedance matching layer structure. The multi-layered structure provides for optimal transmission of an electromagnetic signal for wide angles of incidence, and displays minimal sensitivity to the polarization of the signal.
