Non-attached tire monitoring device
First Claim
1. A non-attached monitoring device for monitoring an engineering condition of a tire and transmitting data related to the engineering condition to a reader positioned outside of the tire;
- the tire having a sidewall that is an oriented attenuating body for the monitoring device;
the oriented attenuating body having maximum and minimum attenuating levels;
the non-attached monitoring device being loosely disposed within the tire;
the monitoring device including a monitoring assembly and an antenna;
wherein the improvement comprises;
the antenna having an orientation that radiates a transmission pattern;
the transmission pattern having a portion that is attenuated by the oriented attenuating body of the tire sidewall at the minimum attenuating level regardless of the orientation of the monitoring device with respect to the tire sidewall.

Abstract
A non-attached monitoring device includes monitoring assembly and an antenna configured to radiate signals from the monitoring assembly. The antenna is configured to radiate through the oriented attenuating body of the tire sidewall regardless of the position of the monitoring device with respect to the tire sidewall. In one embodiment, the antenna has a body that is looped back on itself. The body may be parallel to or perpendicular to the antenna ground plane. In another embodiment, a radiating slot antenna is configured to provide transmissions through the tire sidewall regardless of the position of the monitoring device.
