Vertical Polarized Helicoid Array With Full Azimuth Beam-Scanning
Abstract
This paper outlines the theory behind helicoid antenna array beamforming and the practical validation on an 8x8 helicoid antenna array. Design, simulation, and measurement are presented at 2.45 GHz. A practical method for obtaining the phase steering weights required to perform beam pointing over 360 degrees is presented. A specialised dipole was also developed, achieving 4.9 dBi and low mutual coupling. It was also shown by analysis, simulation and measurement that this type of array, unlike a planar array, does not exhibit beam pointing error, making it highly attractive for retrodirective applications when precision beam pointing is required.
