ABSTRACT:
A multifilar helix antenna includes helical antenna filaments, each filament having a square waveform pattern along its length, resulting in reduced axial length. A multifilar helix antenna according to the invention includes helical antenna filaments, each filament incorporating a microstrip spur-line band stop filter enabling multi-band operation.
