The far-field antenna measurement offers a quick estimation of antenna performance. The traditional far-field concept demands a large separation between transmit and receive side, which is practically impossible for large size of antenna at higher frequencies. The reflector-based compact antenna range offers all the advantages of far-field and simulate a far-field equivalent environment in a very compact indoor test chamber.
The additional advantages offered by Compact range are control temperature, no wind deflection, avoided rain, 24x7 operation ability and also reduces the maintenance costs. We offers Custom models of different sizes can also be manufactured to meet specific customer requirements upto 220GHz.
BBPl has the capability to deliver high planarity (30 micron RMS) reflectors panels upto size of 7.0 m X 3.0 m to construct the range reflector optics. We are capable to take turnkey project including the engineering, manufacturing and installation of reflectors, multi-axes positioning system, and integrated measurement test setup and data acquisition system software.
The lowest operational frequency of any Compact range system is determined by the length of serration, its shape and size of reflector. Similarly, the highest operational frequency is determined by the final machined reflector surface accuracy. The dual reflector system will be illuminated by dual polarized corrugated range feed having cross-polarization better than 40dB.
