Abstract
A zero-bias dual-mode mixing antenna for wireless transponders is proposed in this paper. Designed over an Enhancement-mode Pseudomorphic HEMT (E-PHEMT), the mixer takes advantage of the device nonlinear characteristics around cold operation. Simple closed form expressions, obtained from time-varying circuit analysis, predict good conversion e-ciency in two difierent operating modes without requiring DC bias. For validation, a lab prototype has been implemented and tested, to be flnally integrated in a compact active printed antenna suitable for wireless sensor networks or other radio frequency identiflcation (RFID) applications.
