AI Technical Summary
Existing helical antennas suffer from limited bandwidth and unsatisfactory performance across operational frequency bands, particularly in unifiliar and bifiliar designs, with uniform diameter and inter-turn spacing configurations offering only marginal improvements.
A unifiliar axial mode helical antenna with a monotonously decreasing transverse cross-sectional area and inter-turn spacing from the back end to the front end, featuring a single wire wound in a helix with varying diameters and spacings, optimized for a specific frequency band.
The proposed design achieves a significantly enhanced gain bandwidth from 2200MHz to 7000MHz and superior VSWR performance, with improved radiation patterns along the main axis compared to prior art antennas.
