Sensor with tail or transmission line for vehicle leak testing
First Claim
1. A method comprises:
- sending, by a reader, a first radio frequency (RF) signal to a first wireless sensor that includes a first antenna having a first tail section and a first head section, wherein the first tail section is for placement in a radio frequency (RF) limited area for sensing moisture in a first location of a vehicle under test, and wherein the first head section is for placement in a non-RF limited area; and
receiving, by the reader, a first RF response to the first RF signal from the first wireless sensor, wherein the first RF response includes an indication of adjustment of one or more RF characteristics of the first wireless sensor, wherein the adjustment corresponds to a variance of the one or more RF characteristics from a desired value of the one or more RF characteristics, and wherein the variance corresponds to a level of moisture at the first location;
outputting, by the reader, a message regarding the level of moisture at the first location.

Abstract
A method includes sending, by a reader, a radio frequency (RF) signal to a wireless sensor that includes an antenna having a tail section and a head section. The tail section is for placement in an RF limited area for sensing moisture in a first location of a vehicle under test and wherein the head section is for placement in a non-RF limited area. The method further includes receiving, by the reader, an RF response to the RF signal from the wireless sensor. The first RF response includes an indication of adjustment of one or more RF characteristics of the wireless sensor, which corresponds to a variance of the one or more RF characteristics from a desired value, which, in turn, corresponds to a level of moisture at the first location. The method further includes outputting, by the reader, a message regarding the level of moisture at the first location.
