Abstract

Antenna,which also called an aerial,is a conductor that can transmitting and receiving signals such as microwave,radio or satellite signals.In transmission,a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals,and the antenna radiates the energy from the current as electromagnetic waves (radio waves).A planar or patch antenna is a low-profile antenna that has a number of advantages over other antennas.It is light weight,economical,ease to fabrication and easy to integrate with the accompanying electronics.However,planar patch antennas suffer from more disadvantages as compared to conventional antennas such as less efficiency and low gain. Therefore,in this project,U slot planar antenna is used due to the fact that overcoming in increasing the gain.U slot planar antenna was designed with the added of air gap between the patch and the ground by using the copper annealed materials.The simulation was using the CST Studio Suites software which is a specialist tool for designing a 3D EM simulation.The simulation was done to analyze the perfonnance of the U slot antenna especially the bandwidth of the return loss,the gain and the directivity.
