Abstract
A planar flexible ultra-wide band (UWB) RF antenna includes a flexible non-electrically-conductive substrate and at least one antenna patch having electrically conductive metal positioned on one side of the flexible non-electrically-conductive substrate and having geometry defining a wirelessly transmitted UWB signal. The antenna may electrically couple with an RF transmitter circuit formed on a second side of the flexible substrate and controlled by a microcontroller circuit, formed on the second side, to transmit a radio signal. The RF tag may include at least one decoupling circuit directly electrically connected to the RF antenna and having a decoupling frequency that is different from a transmitting frequency of the antenna. The decoupling circuit transfers power from the antenna when the antenna receives capacitive power from an external non-electrical contact charger operating at the decoupling frequency and having at least one plate of similar geometry to the at least one antenna patch.
