摘要： An antenna includes a receiver, a horn, a lens, and an anti-reflection layer. The horn has a first end disposed on the receiver and a second end defining an aperture positioned opposite the receiver. The lens is disposed within the aperture of the horn and has a first surface facing inward toward the receiver and a second surface opposite the first surface and facing outward away from the horn. The anti-reflection layer includes a dielectric material and is disposed on the first surface of the lens. Moreover, the anti-reflection layer defines holes arranged in a 50/50 material to void ratio and that have a thickness of a quarter wavelength of a signal received by the antenna.

摘要： A broadband or multiband antenna for microwaves, optical transmission or mobile telephones in which a reflector plane and at least one radiating element disposed in the vicinity of the reflector plane are provided. An assembly of defective PFB material elements is superposed on the reflector plane and the radiating element. Each defective PFB material element is substantially plane, parallel to the reflector, and presents at least one characteristic of magnetic permeability, of dielectric permittivity, and/or of thickness in the direction perpendicular to the reflector that differs from one defective PFB material element to another. The assembly forms a leaky resonant cavity.

摘要： A monoconical antenna comprises: a substantially conical concavity formed in one end face of a dielectric; a radiation electrode provided on the surface of the concavity; and a ground conductor provided in proximity to and substantially in parallel with the other end face opposite the one end face of the dielectric. The monoconical antenna is so constituted that electrical signals are fed to between the near vertex region of the radiation electrode and the region of the ground conductor. The half-cone angle α of the substantially conical concavity formed in the one end face of the dielectric is determined by a predetermined rule corresponding to relative dielectric constant εr. Thus, the quality of wideband characteristics inherent in the monoconical antenna can be sufficiently maintained, and further size reduction can be accomplished by dielectric loading.

摘要： A lens antenna having high antenna efficiency, low sidelobe levels, and that is easily assembled. The lens antenna includes a first horn made of a metallic conductor, a second horn made of a high-frequency absorbing plastic material, and a lens for controlling the power distribution at an aperature of the horn. Screws may be used to assemble the first horn, the second horn, and the lens. Though some of the microwave signals input through the circular waveguide of the first horn are reflected on the surface of the lens, most of the microwave signals are absorbed by the second horn. Moreover, because no wave absorber is bonded to an inner wall of a conical horn, nothing screens the microwave signal, the power density distribution at the aperture of the lens is not disrupted. Therefore, it is possible to obtain a desired power density distribution.
摘要翻译： 天线效率高，旁瓣电平低，易于组装的透镜天线。 透镜天线包括由金属导体制成的第一喇叭，由高频吸收塑料材料制成的第二喇叭，以及用于控制喇叭的温度下的功率分布的透镜。 螺丝可用于组装第一个喇叭，第二个喇叭和镜头。 虽然通过第一喇叭的圆形波导输入的一些微波信号在透镜的表面上被反射，但是大多数微波信号被第二喇叭吸收。 此外，由于没有波形吸收器结合到锥形喇叭的内壁，所以没有屏蔽微波信号，在透镜的孔径处的功率密度分布不被破坏。 因此，可以获得期望的功率密度分布。
