CO-PLANAR BROADBAND ENDFIRE ANTENNAS
Vivaldi Broadband Antennas (VC)
The VC Series Vivaldi Antennas are co-planar broadband endfire antennas engineered for continuous, multi-octave operation across a wide frequency range spanning from 700 MHz up to 10 GHz (with extended options reaching higher microwave bands).
Constructed using precision-machined solid sheet metal or metallized high-frequency dielectric PCB substrates with exponentially flared slotline tapers, Vivaldi antennas provide exceptional scalability, versatile mounting options, and cost-effective ultra-wideband performance for Ground Penetrating Radar (GPR), wideband signal reception, and microwave RF testing.
*Custom frequency tuning, low-dielectric PCB substrates (Rogers/Teflon), and multi-element endfire array configurations are available upon request.
⚡ Next-Gen Engineering Highlights
Exponential Slotline Taper
Continuously expanding slotline geometry ensures smooth impedance transformation and continuous multi-octave bandwidth.
Lightweight & Scalable Build
Precision PCB or sheet metal construction offers an ultra-compact footprint, low aerodynamic weight, and outstanding cost efficiency.
Stable Endfire Radiation
Delivers consistent directional gain (6–14 dBi) along the antenna plane with excellent cross-polarization rejection.
Versatile Microwave Spectrum
Optimized for multi-octave microwave systems from 700 MHz to 10 GHz with stable low VSWR matching.
