Our antennas and filters are field-proven across mission-critical platforms in defense, aerospace, and telecom. We have earned the trust of government agencies, military R&D labs, and Tier-1 telecom providers.
Deployed in the harshest conditions — from Himalayan borders to deep-space cryogenic environments — our systems deliver unmatched reliability, efficiency, and performance.
The TA-1060-15 is a high-gain directional panel antenna engineered for focused, point-to-point coverage in the 1030–1090 MHz band.
The TA-1327-P1430VH is a dual-polarized (V & H) panel antenna engineered for wideband coverage across the 1350–2700 MHz range from a single compact unit.
The TA-031KD0-VNF is an ultra-wideband omnidirectional antenna covering 30–1000 MHz (a 33:1 bandwidth ratio) with ≥-8 dBi gain and full 360° azimuth coverage, spanning HF through UHF in a single unit.
The KT-TBPF-117137-NF is a tunable dual-cavity bandpass filter engineered for the 117–137 MHz VHF airband, delivering low insertion loss and strong out-of-band rejection in a rugged, rack-mountable aluminum housing.
The TA-5875-30D4MIL is a rugged, high-gain parabolic dish antenna engineered for long-range, mission-critical wireless links across the 4.4–5.875 GHz band.
The TA-30512-TRS is an automatic TR (transmit/receive) switch engineered for seamless transceiver operation across the 30–512 MHz band.

We use industry-standard electromagnetic design software such as CST Studio Suite, Keysight EMPro, and Advanced Design System (ADS) for antenna, filter, and system-level simulations. These tools allow us to model complex RF behavior, optimize for gain, isolation, impedance, and field coverage before a single prototype is built, saving weeks of costly iterations.

These tools allow us to model complex RF behavior, optimize for gain, isolation, impedance, and field coverage before a single prototype is built, saving weeks of costly iterations.
Our production facilities are equipped for high-volume manufacturing of both antennas and RF filters, supporting global OEM rollouts and defense programs. With automated machining, PCB assembly lines, and temperature-controlled testing chambers, we maintain high throughput while meeting ISO and MIL-STD quality requirements.
Kavveri operates multiple in-house testing environments:
This enables us to certify performance across a wide frequency range and usage environments before shipping.
Our products are designed and qualified to survive extreme mechanical, thermal, and environmental stress. Whether it’s vehicle-mounted antennas facing shock and vibration or space-bound hardware undergoing thermovac cycling, we ensure compliance with MIL-STD-810, DO-160, and other global ruggedization benchmarks.
We offer NPI programs with quick-turn engineering that allow customers to go from concept to field test in record time. Whether it’s for a defense tender, an aerospace proof of concept, or a telco pilot deployment, our agile development team can deliver working prototypes within weeks, often with multiple iterations to meet tight technical specs.
