Bandwidth enhancement of monopole antenna using split-ring
A bandwidth Enhancement of monopole antenna coupled with two identical parasitic split-rings has been designed and studied. This simple combination can significantly enhance the antenna bandwidth over that of the conventional monopole antenna. It is found that, with suitably chosen antenna dimensions, the impedance bandwidth of the antenna can be increased by 39.45%, almost double that of the monopole antenna alone. The far field pattern of the proposed antenna is basically the same as that of the monopole antenna. The average gain for the loaded structures is 3.8dBi which is quite higher than the unloaded monopole. It is also observed that there is no significant degradation in efficiency, despite of conductor loading.
