Furthermore, 45 degree tabbed elements are joined to the top corners of the triangular section and extend in opposite directions therefrom. The tabbed elements added to the triangular section and to the bar section increase the overall electrical length of the antenna to simulate a physically larger size antenna.

  • Patent number: 9064140
    Abstract: A method for testing remote transponders. In the method, a radio-frequency transponder is excited by sending an excitation command having a minimum threshold transmission power with the aid of a first electromagnetic field and the response of the radio-frequency transponder to the excitation command is measured with the aid of a second electromagnetic field in order to test if a corresponding received power threshold is exceeded. One of the fields is a radiating field and the other of the fields is a reactive field. The need to test transponders separately from other transponders and the need to inactivate or screen other transponders in the vicinity of the transponder being measured is eliminated.

  • Patent number: 9035846
    Abstract: A display device includes a display panel and a directional antenna. The directional antenna is disposed behind or under the display panel for radiating or receiving wireless signals. The radiating path of the directional antenna is at a specific angle with respect to a horizontal plane for receiving surrounding wireless signals. Or, the signals radiated from the directional antenna may be reflected or refracted to regions above or in front of the display device by a back-side barrier or penetrate a back-side barrier which does not cause large electromagnetic degradation, thereby receiving wireless signals originated from the front-side or back-side of the display device.

  • Publication number: 20150116172
    Abstract: An optically transparent conformal polymer antenna and a method for producing the antenna from optically transparent conductive polymers. The method includes selecting an antenna design; providing an optically transparent conductive polymer material capable of being printed using an ink-jet printer device; and printing layers of the polymer in the desired antenna design pattern onto a substrate. The surface tension of the polymer solution is adjusted to allow the material to pass through a printer head for printing on a flexible substrate. The material is modified to have a higher conductivity than regular conductive polymer materials so that a suitable antenna may be formed.

  • Publication number: 20150109177
    Abstract: A compact multi-band antenna structure consisting of overlapping elements formed like tree rings is described. A dipole multi-band antenna includes a first arm having a first conductive cylinder with a predetermined length corresponding to a first frequency and a second conductive cylinder having a predetermined length corresponding to a second frequency positioned over the first conductive cylinder without contact between the first conductive cylinder and the second conductive cylinder. A first end of the first conductive cylinder is in the same plane as and is electrically coupled to a first end of the second conductive cylinder. A second arm is similarly formed. A feed line is coupled to the first and second conductive cylinders and to the cylinders in the second arm. Additional frequencies may be added by similarly stacking additional conductive cylinders. The structure is also applied to monopole, circular, spiral, helical and slot antennas.

  • Patent number: 9007272
    Abstract: A portable unit with an endfire antenna and operating at 60 GHz makes an optimum communication channel with an endfire antenna in an array of antennas distributed over the area of a ceiling. The portable unit is pointed towards the ceiling and the system controlling the ceiling units selects and adjusts the positioning of an endfire antenna mounted on a 3-D adjustable rotatable unit. Several transceivers can be mounted together, offset from one another, to provide a wide coverage in both azimuth direction and elevation direction. These units can be rigidly mounted as an array in a ceiling apparatus. The system controlling the ceiling array selects one of the transceivers in one of the units to make the optimum communication channel to the portable unit. The system includes the integration of power management features by switching between Wi-Fi in favor of the 60 GHz channel.

  • Patent number: 8989289
    Abstract: A method and system for transmitting three distinct electromagnetic signals on a same frequency are provided. One or more transmitting devices transmit a first data signal and an inverse of the first data signal in two orthogonal linear polarities of an antenna maintaining their inverted phase relationship and a same amplitude as propagated. Transmitting devices also transmit a second data signal in a linear polarity with a 45 degree rotation around the transmit axis of the first data signal. Transmitting devices also transmit a third data signal in linear polarity orthogonal to the second data signal and consequently 315 degree rotation around the transmit axis from the first data signal.
