Choosing the Right RF Antenna

Critical Factors for Wireless Link Success Selecting the correct radiator is vital for your RF system integration services. Our RF & microwave product expert team recommends focusing on these radiation parameters: Frequency Range & Bandwidth: We offer antennas covering wide frequency range RF parts, from narrowband TETRA band to ultra-wideband (UWB) solutions for EW systems. Gain & Directivity: Choose high-gain horn antennas for point-to-point microwave communication parts or omni-directional designs for RF solutions for wireless networks. Polarization: Available in Linear, Circular (RHCP/LHCP), and Dual-Polarized configurations to match your satellite communications and signal-multiplexing needs. Environmental Ruggedness: Built as high reliability RF parts, our antennas feature radomes and specialized coatings for aerospace and maritime deployments.

RF Antenna Technical Questions

What is the difference between an Active and Passive Antenna?
Passive antennas rely solely on their physical design for gain. Active antennas include integrated low noise amplifiers (LNAs) to boost weak signals, common in RF infrastructure components and GPS/GNSS receivers.
Yes. Our high-frequency horn antennas and patch antennas are optimized for 5G mmWave testing, providing the narrow beamwidths and high gain required for lab RF test components.
A high VSWR indicates that power is being reflected back to the high power RF amplifiers instead of being radiated. Our antennas are precision-tuned to maintain a low VSWR across the entire operating band.

What Our Customers Say

“The gain flatness on RFComp’s broadband horn antennas is industry-leading. They are our primary RF technology supplier for our electromagnetic compatibility (EMC) test labs.”
