Biconical Antennas
Biconical antennas are dipole antennas that consist of two roughly conical conductors nearly touching each other at their points. Due to their double conical design, a wider bandwidth is achieved, which makes them suitable for broadband testing, immunity testing in EMC, antenna measurement systems, and wireless infrastructure.
Similar to dipole antennas, these antennas have an omnidirectional radiation pattern in the H-plane. A coaxial feed line is connected to the center of the antenna at a point where the two cones meet. The input signal carried by this feed is sent to the two cones, which convert the signal into electromagnetic waves for transmission.
Selecting Biconical Antennas
When selecting a biconical antenna, it is important to know the parameters that you need to specify. Below is a list of the key parameters to look out for when selecting this antenna:
Frequency: This is the frequency range over which the antenna can operate.
Gain: It is the ratio of the power delivered in the desired direction to the power radiated equally in all the directions from an isotropic antenna.
Efficiency (in %): It is the ratio of power radiated by the antenna to the power supplied to the antenna.
VSWR: It is the ratio of the amount of power reflected back to the input to the incident power. This parameter is represented as 1.5:1, 2.4:1, 5.6:1 etc. Generally, the more the VSWR, the higher the reflected power, and the lower the antenna performance.
Type of Polarization: It is the orientation of the electric field radiated from the antenna with respect to the antenna axis. Different polarization types exist, such as linear, circular, RHCP, LHCP etc.
Mounting Types: Biconical antennas are available in several mounting types such as tripod mount, clamp mount, connectorized mount, NMO mount etc.
everything RF has listed several biconical antennas from the leading companies. You can compare products, view their specifications, and narrow down on products based on the frequency range, gain, polarization, and other parameters. Once you find products that you need you can view product specs, download datasheets, request a quotation or more information on a product. Your inquiry will be sent to the manufacturer who will get back to you with the required information.
