The Biconical Antenna is a broadband dipole antenna featuring two conical radiating elements arranged coaxially point-to-point. Exhibiting a bandwidth of three octaves or more with coverage from 20 MHz to 18 GHz, it delivers omnidirectional radiation in the H-plane and figure-eight pattern in the E-plane. It is the industry-standard antenna for EMC/EMI compliance testing per MIL-STD, FCC, and CISPR specifications.
Product Overview
Biconical Antenna is a broadband dipole antenna consisting of two conical conductive elements arranged coaxially with their apices nearly touching.As a non-frequency-dependent antenna, it maintains stable impedance and radiation characteristics across an exceptionally wide frequency range—typically three octaves or more—significantly outperforming traditional half-wave dipole antennas.
Key Features
Exceptional Bandwidth: Delivers three or more octaves of frequency coverage, typically from 20 MHz to 1 GHz and up to 18 GHz in advanced models.
Omnidirectional H-Plane Pattern: Provides uniform 360° coverage in the horizontal plane, ideal for field surveys and spectrum monitoring.
Figure-Eight E-Plane Pattern: Similar to a half-wave dipole, with predictable radiation characteristics for precise measurements.
Non-Frequency-Dependent Impedance: For an ideal infinite biconical antenna, input impedance is determined solely by the cone angle, independent of frequency—a key advantage for broadband matching.
Integrated Balun: Built-in balanced-to-unbalanced transformer ensures proper impedance matching to 50 Ω coaxial systems.
Compact & Portable: Lightweight construction with foldable element options for easy storage and field deployment.
High Power Capability: Select models support high-power immunity testing applications.
Applications
EMC/EMI compliance testing (radiated emissions & immunity) per MIL-STD, FCC, CISPR
Normalized Site Attenuation (NSA) measurements and site evaluation (CISPR 16-1-4)
Spectrum monitoring and field survey
