Helix Antenna

Helix antennas are used in space applications, satellite systems, radar systems, TV signal transmission, etc. Usually, a helix is manufactured as a wire, coiled around dielectric cylinder. Main characteristics of helix antennas are:
• Circular polarization,
• Broad-band,
• Two operation modes depending of used frequency,
• For unifilar helices, using a reflector is necessary.
Several models of helix antennas are created and simulated in WIPL-D Pro and presented here ... read more

Spiral Antenna

Main characteristics of spiral antennas are:
• Circular polarization,
• Broad-band,
• Low directivity.
Models of duofilar spiral antennas, simulated in WIPL-D Pro are presented here. Our aim is to investigate the influence of the dielectric and to compare simulation times and numbers of unknowns for two antenna models. We will observe the gain from 1 GHz up to 5 GHz (D, E, F and G bands). In WIPL-D Pro, helix antennas can be designed using the built-in Helix object. ... read more
