Pattern-Steerable Endfire Plasma Array Antenna

The modification of a conventional plasma window antenna (PWA) into a novel endfire plasma array antenna (E-PAA) and the comparison of their performances are first made. It will be shown that the E-PAA provides better performance than the PWA does. Then, the gain improvement and more importantly the radar cross section (RCS) reductions for stealth properties of the E-PAA are described. A type of feeding and generating system of plasma antenna is given. Simulated and measured results at 300 MHz are discussed, indicating the potential applications of the E-PAA in high-level integrating of radio transceivers onboard for wireless communications.
