Gain Enhancement Of A Plannar Monopole Antenna With Circular Shape Using Artificial Magnetic Conductor (amc) Structure For Ultra-wideband (uwb) Applications

Abstract

Abstract Ultra-wideband (UWB) antennas that are more widely developed and needed in modern times such as this have many advantages. Having a very wide frequency range of 3.1GHz-10.6GHz makes this antenna has added value at an unnecessary large average cause the efficiency of this antenna is not efficient enough. In addition, directivity also affects the increase in gain, namely the greater the gain, the radiation pattern produced, the energy emitted can focus on the direction of the main beam and the energy can select a larger place.This final project discuss about gain enhancement of plannar monopole antenna with circular shape and Artificial Magnetic Conductor(AMC) ground. By sampling a number of UWB working antenna frequencies it can be seen the average increase in gain of the antenna. For the purposes of validation an antenna is needed to be designed for the prototype to be launched. The prototype be calculated and compared with the simulation results.This result of this final project is the planar monopole antenna with with circular shape using artificial magnetic conductor (AMC)structure for ultra-wideband applications based for the antenna designned and implemented.UWB antenna improves the gain for entire UWB range, a peak gain of 14.51 dBi at 3.6 GHz are obtained.Miniaturized structure with high gain makes this design better candidate,especially for outdoor UWB application.
