    摘要: Each of a pair of antennas for broadcasting has multiple elements arranged vertically on the same tower. The antennas transmit circularly polarized signals of opposite polarization. The opposite circular polarization of the radiated signals increases their mutual isolation and permits broadcast of conventional FM-band signals and digital FM at the same frequency. The polarization technique allows the elements of the two antennas to share an aperture without degradation of function.

    摘要: An antenna system is disclosed that includes a mast, waveguides positioned about the mast, and a feed system positioned external to the mast and between adjacent waveguides, such the feed system can be easily serviced. The waveguides include radiator elements that are easy to manufacture, and thus reduce the cost associated with wideband cavity-backed antennas. Further, adjustable disc-like and spherical radiating elements for exciting the fields in the waveguides are also disclosed. DC voltage buildup on the radiating elements are grounded by an easily attachable coaxial structure.

    摘要: A method for adjusting a detection axis of an object detection system, wherein a disk-shaped adjusting member is fixed to a reference plane on an outer face of a casing, wherein the rotational position of the adjusting member is adjusted. The adjusting member has first and second base surfaces, between which a wedge shape is formed. Rotating the adjusting member finely adjusts the angle of the second base surface relative to the reference plane of the casing, thereby resulting in the direction of the second base surface coinciding with the direction of an object detection axis of a radar mechanism part fixed within the casing. The direction of the object detection axis can be adjusted in the horizontal direction by placing a level on the second base surface of the adjusting member and adjusting the mounting angle of the casing so the level indicates a horizontal direction.

    摘要: A microstrip antenna has first and second cylindrically-shaped dielectric layers having first sides secured together with an array of conducting strips conformally interposed therebetween, the strips being spaced to define a slot between each pair of adjacent strips. A conductive ground plane is disposed on an interior second side of the first dielectric layer, and an array of spaced apart radiating patches are conformally disposed on an exterior second side of the second dielectric layer, each of which patches is positioned over a corresponding slot. Responsive to electromagnetic energy, a high-order standing wave is induced in the antenna and a directed beam is transmitted from and/or received into the antenna.

    摘要: An identification appliance, such as a wristband, bracelet, patch, headband, necklace, card, sticker, or other wearable appliance, has an improved patch or microstrip antenna. The microstrip antenna comprises a conductive patch layer, a conductive ground layer and a dielectric layer in between the conductive layers. The microstrip antenna is mounted to or disposed in the identification appliance, where preferably the ground layer is closest to the user and the patch layer is furthest from the user. Electronic circuits may be located in the dielectric layer, on a surface of a conductive layer, or on another part of the identification appliance. Connecting holes through the dielectric layer may allow circuits to be connected to a conductive layer or layers. This improved antenna resolves detuning and communication degradation problems.

    摘要: A radio frequency (RF) antenna of the present invention generally comprises an electrical conductor and a unitary metallic surface mounting structure. The electrical conductor, which performs the radiator function, is secured to the surface mounting structure so that the electrical conductor may use the surface mounting structure not only as a surface mount but additionally as a ground plane. The surface mounting structure is presented in a cross-configuration having outward extending arms. The arms perform the ground plane function and are bent to a desired angle to produce a desired radiation pattern and/or impedance. A plastic radome with a metallic insert is preferably used to cover the electrical conductor and to secure the electrical conductor to the surface mounting structure.

    摘要: An antenna assembly for wireless communications has various components to minimize signal influence when transmitting signals to minimize undesirable loop formation phenomena caused by (positive) feedback of signals. Signal wave scattering and diffraction causing back lobe radio frequency (RF) patterns are minimized by a particular antenna assembly structure having a reflector and at least one attenuating structural member, a metallic mesh wrapping the power cable of a feeder, a non-conductive antenna support structure, or any combination thereof. The dimensions of the various components, in particular the reflector and attenuators, can be varied according to desired wireless communications environment.
