Abstract
A transponder module includes a circuit board having top and bottom surfaces and an inverted-F receive antenna formed on the circuit board. The receive antenna includes a ground plane formed on one of the surfaces and an active element formed above the ground plane. The module also includes a RF engine having an input coupled to the receive antenna, an output and a power supply input. The module additionally includes a RF decoupling network having first and second ports. The first port is coupled to the output of the RF engine. The module further includes an inverted-F backscatter antenna coupled to the second port of the RF decoupling network. The backscatter antenna includes a second ground plane formed on one of the surfaces and a second active element formed above the second ground plane. A method of tagging an object having a conductive surface includes coupling a transponder module including a low profile antenna to the conductive surface such that a ground plane contained in the transponder module is adjacent the conductive surface of the object and transmitting a signal from the low profile antenna to an interrogator, the signal including information relevant to the object.
