Rectangular printed loop microstrip patch antenna for wireless communication at 2.4 GHz operating frequency / Mohd Razuan Abd Razak

A rectangular microstrip loop patch antenna for wireless communication system at 2.4 GHz operating frequency is proposed and analyzed. The objectives of this project are to design and analyze both simulation and measurement results for the proposed antenna to make comparison. The design is fabricated on FR4 substrate of dieletric constant, er equal to 5.0 and tangent loss 0.025. A combination of several equations and technique are used to get the initial geometrical parameters. The antenna can operate at 2.4 GHz within the desired specification by adjusting the dimensions. The antenna has return loss of-14.781 at 2.401 GHz for simulation and -13.692 t 2.513 GHz for measurement. The voltage standing wave ratio, VSWR is1.443 for simulation and 1.521 for measurement. The antenna has an omni-directional characteristic. The design and simulation are done using Computer Simulation Technology CST Microwave Studio software and the measurement using Vector Network Analyzer (VNA). The design procedure, simulated and measured has been discussed in this paper
