A system with one or more transceiver antenna assemblies for installation in vehicle side-view mirrors to enable communication with nearby vehicles. Each transceiver antenna assembly may have one or two antenna arrays implemented on a single printed circuit board, protected by an antenna housing used to mount the transceiver antenna inside the mirror assembly. Each antenna array in a dual-channel transceiver antenna may transmit and receive data over one of two DSRC channels. One channel may be used to transmit and receive vehicle data only and the other channel may be used to transmit and receive both vehicle data and audio/video (A/V) data. Each antenna array is connected to a radio in the vehicle that processes received signals and prepares signals for transmission. Such a transceiver antenna system may be especially useful for communication in truck platooning.

A temperature measurement system capable of operating in harsh environments including a temperature sensor having an antenna, diode, and dielectric layer disposed on the object of interest is provided, wherein the antenna includes a buried portion that extends through and is electrically coupled to the object of interest, and an exposed portion disposed upon an outer surface of the dielectric layer and the diode is coupled between the object of interest and the exposed portion of the antenna. The antenna is configured to receive interrogating signals from a transmitter, and to transmit response signals corresponding to the resonant frequency of the temperature sensor and its harmonics, which are indicative of the measured temperature of the object of interest. A receiver detects the response signals and correlates the frequency to a known temperature response of the dielectric material. Methods of making and using the temperature measurement system are also provided.

A J-Pole antenna disclosed including: shunt segment extending out of the plane of the J-Pole antenna. A shunt segment extending out of the plane of the J-pole antenna aids in attaching the antenna to a connector and allowing for a reduction in the size of the antenna and connector. The shunt segment also makes the antenna shorter while preserving the same gain and impedance performance as a conventional J-Pole antenna. A connector plate and connector may be used with the antenna having the shunt segment extending out of the plane of the J-Pole antenna. A protective enclosure may be used with the J-Pole antenna and allowing a radiating antenna segment of the J-Pole antenna to extend from the protective enclosure.

Method and system for passive wireless strain gauge

The present invention provides an aperture-fed patch antenna assembly that is recessed into a conductive surface of an external shell of an electronic device. In one embodiment, an antenna feed attached to a removable core of the electronic device may be removed from the external shell without requiring a manual disconnecting of the antenna feed from a wireless radio modem in the electronic device. The patch antenna assembly includes a shim having an aperture therein and positioned between a primary dielectric and a printed circuit board to create a secondary dielectric between the primary dielectric and the printed circuit board. In one embodiment, the primary dielectric is ceramic and the shim is plastic.
