Dual Linearly Polarised Antennas

 

Steatite Antennas produces a wide range of Dual Linearly polarised antennas from 0.2 -40 GHz in a number of antenna packages such as Sinuous, Quad ridged and reflector / feed combinations. Dual Linear antennas offer a number of benefits such as polarisation diversity, the ability to operate on two channels simultaneously using one set of equipment. With two uncorrelated signals one channel may be used to transmit whilst the other is used for receive, thus allowing for a duplex communication link.

In antenna test ranges the use of a dual linear source antenna allows the polarisation to be remotely changed without the requirement to physically rotate the antenna. Co-polar and cross-polar measurements can be made without physically accessing the source antenna, allowing the full scattering matrix to be determined.

When a dual linear antenna is used in a monitoring role, where the polarisation is not known, the dual linear antenna may offer the opportunity to simultaneously monitor both vertical and horizontal polarisations
