Com-Power Corporation
Biconical antennas are used for emissions and immunity testing to meet various EMC standards specified by FCC, CISPR and EN. The broadband characteristics of the biconical antenna make it a good choice for making sweep measurements and for automated measurement systems.

A.H.Systems, Inc.
For many years most standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz. However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas began to be accepted. Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems'' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each Biconical antenna will provide reliable, repeatable measurements.

Biconical Antennas have dipole like characteristics (e.g. circular directional pattern in the H-plane,"8"-shaped in the E-plane, fixed phase center, comparable gain), with an enormous wide bandwidth achieved by the double cone elements. One of the earliest and worldwide most popular biconical antenna designs is the BBA 9106 with balun VHA 9103 B. During the last years a growing need for expanded frequency ranges arised, which led to the design of biconical antennas reaching down to frequencies of 20 MHz and up to 18 GHz and above. A further increase of bandwidth was achieved with qualified 4:1 baluns, providing a typical gain increase of approx. 6 dB at the lower frequency range. The biconical elements can be mounted and dismounted within a few seconds providing perfect contact repeatability thanks to special clamping fixtures. A small wrench made of insulating material is supplied with the balun, it is tied to the balun head and thus always available whenever needed. Biconical antennas can be used for many applications, in which half-wave dipoles have been used traditionally. An enormous reduction of measurement time can be achieved, because the time consuming tuning of the antenna elements to the half wavelength is not needed, an important condition for sweeped broadband measurements. In typical dipole applications several discrete frequencies are measured, in contrast the biconical antenna allows continuous sweeps, where site anomalies are discovered much easier.

BBM-1 -
ROM-Elektronik GmbH
The handy biconical EMC antenna BBM-1 is THE answer to be able to carry out inexpensive yet highly precise measurements in the lower frequency range from 50 MHz to 2500 MHz.The high-quality, "radial-isotropic" EMC measuring antenna BBM-1 is very light and therefore, in addition to use in the laboratory, also ideally suited for portable measuring devices.Each biconical EMC antenna has a high-quality SMA connector and can therefore be connected immediately to many spectrum analyzers. Devices with N-connection can be connected via our optional adapter.

EM-6917B-1 | 30 MHz To 3 GHz -
Electro-Metrics Corp.
The EM-6917B-1, a hybrid combination of the industry standard biconical and log periodic antennas, delivers an unmatched combination of frequency coverage and high power handling capability. Featuring exceptionally broad frequency coverage of 26 MHz to 3 GHz, the EM-6917B-1 eliminates the need for adjustments or switching antennas in most test applications up to 3 GHz, and it does so without compromising power handling capability for transmit applications.

EM-6912A | 30 Mhz – 300 MHz -
Electro-Metrics Corp.
A balun, feedline, and element cage give the Electro-Metrics EM-6912A response curves that are almost linear, making it ideal for swept measurements. An added benefit is that the EM-6912A has an improved BALUN design, which makes it insensitive to changes of orientation while vertically polarized. Readings obtained will be the same no matter which element is closest to the ground plane, eliminating a potential source of measurement error.

A typical emi emission test is performed using broadband EMC antennas such as biconical, log periodics, Combilogs and horns. These antennas usually placed at 1, 3 or 10 meter distance as required by the test specification. These is considered far field measurements and the emission limits are given for the specific distance by the specification. During EMI compliance measurements, the emissions levels from products are compared with these limits. If the product exceeds these limits it is considered failing. These tests are typically conducted in a open area test site IOATS) or inside an anechoic chamber.
