Hyperband Bi-Conical Antenna Design Using 3D Printing Technique

[摘要] We combined a 3D printing technique with conductive paint for an antenna manufacturing methodology. The performance of the approach is evaluated through a 3D- printed and coated bi-cone antenna. The antenna far-field pattern and efficiency are measured using near-field spherical scan and reverberation chamber techniques. Good agreement is seen between measurements and simulations and an impedance bandwidth of at least 34:1 is achieved. An extruded bi-conical antenna geometry is also studied for bandwidth extension to lower frequency and an impedance bandwidth of 58:1 is realised.
