Design & Implementation of Archimedean Spiral Antenna with FR4_EPOXY Sheet
Abstract
A circularly polarized Archimedean spiral antenna has been designed with return loss is less than -10dB. In this antenna, polarization, radiation pattern and impedance matching remain unchanged over a large bandwidth. This spiral antenna is basically circularly polarized over a wide band. It operates at the frequency from 700MHz to 1.5GHz. It is being designed using HFSS (High-Frequency Structural Simulator) to analyze the parameters of the antenna. Antenna parameters such as Return Loss, Gain, Radiation Pattern were measured. Keywords - Archimedean Spiral Antenna, Circular Polarization, Large Bandwidth, Impedance Matching
