An Improved Model for Static Field Micro-Particle Components on a Printed Transmission Line

Amongst existing RF switching methods, a directly connected biasing circuitry is not required for Static Field Micro-Particle Components (SFM-PCs); therefore, not only power consumption is lowered but also these particle-based switches can be used in complex geometries. In this paper, an improved model for SFM-PC was presented and the effects of its physical characteristics on the performance of a microstrip TL was investigated. HFSS simulations and measurements reveal that the frequency bandwidth of both ON and OFF states varies with its physical characteristics; this mandates a careful design to meet the requirements of different wireless communication systems.
