Biconical antennas are widely used in RF testing and measurement where broadband performance, broad azimuth coverage, and flexible system integration are important. With models designed for applications ranging from lower RF frequencies to microwave, millimeter-wave, and selected sub-THz bands, the RF MISO Biconical Antenna Series provides engineers with a broad range of options for different frequency, polarization, and interface requirements.
Rather than relying on a single antenna to cover the entire spectrum, the RF MISO series includes multiple models covering selected frequency bands from 0.02 GHz up to 303 GHz. This gives engineers the flexibility to select an antenna according to the actual operating band and measurement environment.
Broadband Coverage for Different RF Applications
Frequency range is usually the first consideration when selecting a biconical antenna. The RF MISO series includes models covering a variety of operating bands, from low-frequency broadband systems to high-frequency millimeter-wave and sub-THz applications.
For example, the RM-BCA0023-2 operates from 0.02 to 3 GHz, while models such as the RM-BCA120-2 and RM-BCA245-3 extend operation to 20 GHz and 45 GHz, respectively.
For higher-frequency applications, the RM-BCA10110-4 covers 10 to 110 GHz, while the RM-BCA300-3 is designed for operation from 297 to 303 GHz.
This wide model selection allows engineers to choose a frequency range that matches the target measurement or RF system instead of compromising performance with an unsuitable antenna.
Broad Azimuth Coverage
A key characteristic of the RF MISO biconical antenna family is broad azimuth coverage.
Depending on the model, these antennas are suitable for RF systems where signals need to be transmitted or received over a wide horizontal angular range. This makes the series useful for broadband signal monitoring, surveillance, direction finding, reconnaissance, and various RF measurement environments.
In antenna laboratories, biconical antennas can also be used for gain comparison, radiation pattern measurement, and chamber verification.
Multiple Polarization Configurations
Different RF systems may require different polarization characteristics.
The RF MISO Biconical Antenna Series includes models with vertical linear polarization, 45° slant linear polarization, standard linear polarization, and selected circularly polarized configurations.
For example, several broadband models use vertical or 45° slant linear polarization, while the RM-BCA3537-3, operating from 35 to 37 GHz, provides a dual-circular-polarization configuration.
This range of polarization options gives engineers more flexibility when matching the antenna to the polarization requirements of the surrounding RF system.
Flexible RF Interfaces
System integration becomes increasingly important as operating frequency increases.
Across the series, RF MISO provides a variety of coaxial and waveguide interfaces, including:
- SMA Female
- N Female
- 2.92 mm Female
- 2.4 mm Female
- 1.0 mm Female
- Selected waveguide interfaces
At the upper end of the series, the RM-BCA300-3 uses a WR3 waveguide with a UG-387 flange, providing an interface suitable for its 297–303 GHz operating range.
The availability of different RF interfaces helps engineers integrate the antenna with test instruments, RF front ends, measurement fixtures, and other system components.
Designed for RF Testing and Measurement
Biconical antennas can play different roles depending on the frequency band and system configuration.
Typical applications for the RF MISO Biconical Antenna Series include EMC testing, including radiated emissions and radiated immunity measurements; antenna measurement and gain comparison; radiation pattern measurement and chamber verification; broadband signal monitoring; surveillance and direction finding; reconnaissance systems; and vehicle-mounted, ground-mounted, and integrated RF platforms.
Because the series includes different combinations of gain, VSWR, polarization, RF interface, size, and mechanical configuration, antenna selection should always begin with the target frequency range and then consider the requirements of the complete RF system.
Selecting the Right Biconical Antenna
When choosing a model, engineers should first determine the required operating frequency range, then evaluate polarization and RF interface requirements.
Other parameters such as VSWR, gain, physical dimensions, weight, and power handling should also be considered according to the target application.
For example, lower-frequency models may have relatively large mechanical dimensions, while millimeter-wave and sub-THz models can be significantly more compact. Interface requirements also change as the operating frequency increases, ranging from conventional coaxial connectors to specialized millimeter-wave interfaces.
RF MISO technical support can assist customers in reviewing frequency range, RF interface, polarization, mounting, and system integration requirements when selecting a suitable biconical antenna.
A Broad Biconical Antenna Portfolio from RF to Sub-THz
From 0.02–3 GHz broadband models to 297–303 GHz sub-THz designs, the RF MISO Biconical Antenna Series provides a diverse selection of antennas for RF engineering, measurement, monitoring, and system-integration applications.
With multiple frequency ranges, polarization configurations, mechanical sizes, and RF interfaces available, the series gives engineers the flexibility to select an antenna according to the actual requirements of the test environment or RF platform.
