Abstract: The circular helix is a popular structure for application in broadband, circularly polarized antennas. However, it is not amenable to fabrication using printed-circuit or micro-fabrication techniques. On the other hand, a rectangular helix structure is amenable to fabrication using printed-circuit techniques and can be planar. Printed-circuit techniques are important for miniaturization as well as low-cost mass-production. Moreover, the rectangular helix structure retains the most important properties of the conventional circular helix. The project mainly involves examination of the radiation characteristics of the rectangular helix as a function of the structure parameters such as dimensions, pitch angle, aspect ratio, dielectric substrate etc. Effort will also be required to develop an efficient excitation (or feed) arrangement. Attempt will be made to develop an antenna suitable for GPS or satellite communication. The project includes simulation using CAD tools (CST Microwave Studio), fabrication, and testing of an antenna.
