A narrow impedance bandwidth is the most serious limiting factor of linearly polarized antennas. The problem of designing a wideband antenna is generally studied in the context of loading the antenna with lumped circuit elements. It is a very difficult task to synthesize loaded wire antennas to achieve a broad-band operation, if one chooses to include a matching network, load circuit and the ability to determine proper locations of the load. In this paper a simple and efficient technique for improving the impedance matching of a class of wide band antennas is presented. These antennas have impedance characteristics that exhibit dual (or multiple) resonance. The results obtained are compared between the matched and without matched antennas. This shows the improvement.
