When working in the 30–40 GHz millimeter-wave band, engineers often need an antenna that is not only compact and easy to integrate, but also stable enough for repeatable RF testing. RF MISO’s RM-BCA3040-4 Bi-Conical Antenna is designed for this type of high-frequency test environment. It operates across the 30 GHz to 40 GHz frequency range and provides vertical linear polarization with a typical gain of 4 dBi.
For many microwave and millimeter-wave applications, the antenna is the first point where free-space signals enter or leave the test system. A small change in antenna performance can influence the reliability of measurement results. The RM-BCA3040-4 is suitable for engineers who need a practical antenna solution for EMI detection, direction finding, reconnaissance, antenna gain measurement, and radiation pattern measurement.
This antenna uses a 2.92 mm female RF connector, which is commonly used in high-frequency microwave test setups. The connector interface allows the antenna to be connected with compatible test cables, RF instruments, and measurement systems. For laboratory testing or system integration, this makes the RM-BCA3040-4 easier to deploy in a controlled measurement chain.
With a typical gain of 4 dBi, the antenna offers a useful balance between signal coverage and directional performance. It is not intended to be an extremely high-gain narrow-beam antenna. Instead, it provides a practical radiation characteristic for applications where engineers need stable signal transmission or reception across the 30–40 GHz band.
The vertical linear polarization of the RM-BCA3040-4 is also important in antenna measurement and RF system verification. In real test environments, polarization alignment can directly affect received signal level and measurement accuracy. By using a clearly defined polarization structure, the antenna helps engineers build more consistent test conditions.
Overall, RF MISO’s RM-BCA3040-4 Bi-Conical Antenna is a reliable choice for 30–40 GHz millimeter-wave applications. Its defined frequency range, vertical linear polarization, 4 dBi typical gain, and 2.92 mm female connector make it suitable for EMI detection, direction finding, reconnaissance, antenna gain testing, radiation pattern measurement, and other high-frequency RF test applications
