Analysis of Edge Terminated Wide Band Biconical Antenna
Keywords:
Biconical, discontinuity, loop, return loss, terminationAbstract
A finite length biconical antenna has standing waves existing due to its abrupt discontinuity at the terminals and results in band width limitation. An appropriate termination of these terminals can enhance its bandwidth to a considerable extent and make it truly wide band. A finite biconical antenna with its edges terminated in thick loop (circular) is proposed and its radiation characteristics are analyzed for different values of ‘?r’. Where ‘?’ is the wave number and ‘r’ is the length of the antenna. Compact antennas for ultra wide band (UWB) and above are in demand for modern communications and the proposed antenna meets the wide band requirement at UWB and above such as X, Ku, K bands with very low return loss.
