Alaris Antennas presents spiral antennas
[Johannesburg, 11 January 2019] -The antenna is designed to use two conductive spiralled arms, extending from the centre outwards.
Alaris Antennas designs and manufactures a range of spiral antennas, which can be customised to suit each client's requirements.
Spiral antennas belong to the class of frequency-independent antennas, which can be designed to operate over a wide range of frequencies. Polarisation, radiation pattern and impedance of these antennas remain relatively stable over a large bandwidth.
The antenna is designed to use two conductive spiralled arms, extending from the centre outwards. The antenna may be a flat disc, with conductors resembling a pair of loose spirals, or the arms may extend in a three-dimensional shape like a spring... [Full Story...]
