Frequency Independent Antennas

Spiral Antenna:

Archimedean Spiral and Equiangular Spiral Antenna has been designed, simulated and fabricated for the 2GHz to 18GHz bandwidth, |Axial ratio| ≤ 3dB and typical VSWR ≤ 2.

15% Reduction in size has been achieved and the parameters of Meander Arm Spiral are better than the classical antenna.
