Reshaped Monopole Antenna structure fit for short range wireless access

Abstract

Monopole antenna acts as an open resonator for radio waves, hence often named as resonant antenna. The operating wavelength defines the length of the antenna. The design approach of reshaped monopole antenna is simple. By employing the design procedures of monopole antenna, modifications are done in the monopole structure in order to enable it resonate at the design frequency of 5.846 GHz. This frequency lies within ISM (Industrial, Scientific and Medical) band and hence it is useful for short range wireless applications. The design of reshaped monopole antenna is implemented using Agilent ADS 2009 and various parameters such as directivity, gain, return loss, radiation pattern are obtained for the designed frequency.
