A novel approach for wideband tunable Electrically Small Antennas

In this paper a novel approach for making Electrically Small Antennas (ESA) is presented. For this purpose a two port configuration is used in which one port is exploited (the secondary port) in order to match the other port (the primary port) to the source. The simulated results shows that the proposed approach not only considerably improves the band width of operation, but also it allows frequency reconfiguration in a wide range.
