Antenna/transceiver configuration in a traffic sensor
First Claim
1. A sensor for obtaining vehicular traffic data, the sensor comprising:
- a housing having a front surface;
an antenna plate disposed within the housing for transmitting radiation to a vehicle through the front surface and for receiving the radiation reflected back from the vehicle through the front surface, the antenna plate having an antenna ground surface and a radiating surface;
a transceiver circuit plate disposed within the housing for electrically driving the antenna plate, the transceiver circuit plate having a component side for supporting circuit components and a circuit ground side for grounding the circuit components;
a processor unit for driving and processing electrical signals from the transceiver circuit plate to obtain vehicular traffic data;
wherein the antenna ground surface is between the radiating surface and the transceiver circuit plate;
wherein the housing includes a first component and a second component attached together at a seal plane, the seal plane being substantially perpendicular to the radiating surface, andwherein the first component and the second component are attached together at a first seal surface and a second seal surface, the first seal surface being substantially parallel to the seal plane, and the second seal surface being oriented at a non-zero angle relative to the seal plane.

Abstract
A sensor for obtaining vehicular traffic data is described. The sensor includes a housing having a front surface. The sensor also includes an antenna plate having an antenna ground surface and a radiating surface. The antenna plate is disposed within the housing for transmitting radiation to a vehicle through the front surface and for receiving the radiation reflected back from the vehicle through the front surface. A transceiver circuit plate is disposed within the housing for electrically driving the antenna plate. The transceiver circuit plate has a component side for supporting circuit components and a circuit ground side for grounding the circuit components. The antenna ground surface is between the radiating surface and the transceiver circuit plate. A processor unit drives and processes electrical signals from the transceiver circuit plate to obtain vehicular traffic data.
