Design and Implementation of Printed Monopole Antenna for ISM Band

Monopole antennas have several advantages but for their narrow bandwidth. Broadband planar monopole antennas have all the advantages of the monopole in terms of their cost, and ease of fabrication besides, yielding very large bandwidths. This paper focuses on designing and simulating printed monopole antenna for ISM band resonant frequency of 2.4 GHz. Design and simulation by using IE3D and hardware implementation by using double sided copper clad on FR4 substrate. For many applications large bandwidth is required. Various planar configurations such as circular, triangular, rectangular and square monopoles have been studied. More recently, it has been shown that, although the square monopole (SM) provides smaller BW than the circular monopole (CM), its radiation pattern suffers less degradation within the impedance BW. It has been observed that printed rectangular monopole antennas are small in size and simple in design and fabrication because of high operating frequency but its performance is very good for ISM band and multiband applications.
