Indra - 1
Indra - PC
SAR for UAV
Slotted Wave Guide Antenna
It gives a rugged structure with low Side Lobe Level, Low loss, light weight and high gain. Slotted Wave Guide antenna are developed for various bands and applications.
LCA - MMR
LCA - MMR
Microstrip Patch Antenna
It is a low profile and light weight antenna with superior electrical performance in terms of its bandwidth and pattern characteristics. It is easy to integrate with MMICs and capable of dual and triple frequency operations.
X Band for BFSR
X Band for Missile
Ku Band for SAR for UAV
It generates different types of beam from same aperture with more volumetric coverage. Very Low Side Lobe pencil beams in azimuth and simultaneously multiple beams during receive mode and shaped beam for required volumetric illumination in transmit mode.
Passive Phased Arrays
It has individual radiators with integrated Phase Control Module, distributed architecture, efficient scan coverage, beam agility and high reliability.
Active Phased Arrays
It has integrated radiators with integrated TRM with solid state technology, distributed architecture, efficient scan coverage and high reliability.
