DESIGN OF PRINTED MONOPOLE ANTENNA FOR MICROWAVE COMMUNICATION

A printed monopole in its planar and vertical configuration has been designed, fabricated and analyzed for microwave applications on low cost FR4 substrate material of thickness, h = 1.56 mm and relative permittivity, εr = 4.3. The designed planar monopole has been simulated and experimented to find its frequency response with coplanar waveguide feed to exhibit dual band characteristics with -10 dB reflection loss bandwidth of 45.078 % (i.e. 1.5:1 between 1.334 and 2.109 GHz) and 114.92 % (i.e. 3.7: 1 between 3.99 and 14.77 GHz). The vertical monopole using the same patch has also been simulated and experimented and -10 dB reflection loss bandwidth of 173.67% (14.2:1 between 0.925 and 13.125 GHz) has been obtained. The antenna finds many applications in microwave bands.
