A Simplified Model for Normal-Mode Helical Antennas

Normal-mode helical antennas are widely used for RFID and mobile communications applications due to their relatively small size and omnidirectional radiation pattern. However, their highly curved geometry can make the design and analysis of helical antennas that are part of larger complex structures quite difficult. A simplified model is proposed that replaces the curved helix with straight wires and lumped elements. The simplified model can replace the helix in the analysis of larger structures that include a helical antenna reducing the computational effort required.
