Abstract
The gain, received power bandwidth, transient characteristics, and signal fidelity of two time-varying electrically small receiving antennas based on parametric amplifier design are studied using practical quadrature amplitude modulation (QAM) signals. Results show that interference from the difference harmonic present in the response of degenerate-mode parametric amplification decreases its signal throughput relative to a reference linear time-invariant (LTI) receiver, despite its apparent increased received power bandwidth in the frequency domain. The analysis also demonstrates that a nondegenerate parametric receiver, lacking this detrimental effect, exhibits increased signal throughput over the reference LTI receiver.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
