Helical antenna for wireless broadband system / Nurul Khalidah Kamarulzailan

Antenna is the basic component of all system using electromagnetic radiation to transmit and receive information. In this project the antenna that has been design is helical antenna. Helical antenna is the antenna that has been popular in application from VHF to microwaves requiring circular polarization. The one that take advantages of helical antenna is satellite communication. A helical antenna is an antenna consisting of a conducting wire wound in the form of a helix. In most cases, helical antennas are mounted over a ground plane. The feed line is connected between the bottom of the helix and the ground plane. The important part of helical antenna is the radiating element which is the helical wire. The helical wire is driven at one end and radiating along the axis of the helix makes the direction unidirectional from the far open end. For this project, theory and practical must be done to know the signal when using helical antenna for broadband wireless system. The antenna is design using CST microwave studio. The antenna will focused on increase the performance of wireless broadband system in term of loss and its gain. The antenna is design for wireless broadband application because of it is easy to construct, low cost, and smaller size. The simulation will be compared to the experimental results. This invention is to provide depth knowledge on helical antenna.`
