2.46 GHz reduce size helical antenna simulation

This paper is to focus on to design of the basic geometry of helical antenna in small size at frequency 2.46 GHz. Several parameters dimensions and helical profiles were studied in order to obtain a suitable frequency range. The software that was applied for this simulation is the CST Microwave Studio (CST MWS) which is analytical tool that provides an accurate 3D EM simulation results for high frequency designs. From the simulation designs, the return losses were obtained. There were less than -8 dB. The results conclude that the helical antenna performed the properties of the 2.46GHz frequency range. From the simulation, the results obtained were S parameter, farfield, bandwidth and gain of the antenna. In a nutshell, all the simulation results of revealed that the designed helical antenna performed at 2.46GHz (Ultra High Frequency (UHF). At this 2.46 GHz can be applied to serve for a number of wireless applications including for WiMAX (Worldwide Interoperability for microwave Access) technologies.
