Dipole antenna for radiated EMC/EMI compliance testing

Our dipole antenna kit is a standard reference antenna set which can be used for calibrating broadband antennas and radiated EMC/EMI compliance testing.

Currently we offer the AD-100 model which includes a variety of antenna elements which span the 30 MHz to 1 GHz frequency range.

The AD-100 set features four differently-sized baluns and antenna elements which are perfect for various E-Field measurements. It comes with an extra-durable, rugged plastic carrying case which keeps your test equipment protected.

The reference antennas included with the AD-100 set are made from high-quality materials and are ideal for daily use in the lab. We also provide to our customer an exclusive 3 year guarantee on all Com-Power testing equipment.

The AD-100 contains four rod elements, two low frequency elements, and two medium frequency elements which are adjustable and tuneable depending on your measurement criteria.

The AD-100 dipole antenna kit complies with ANSI, CISPR, ETSI, and EN requirements and will be supplied with a manual providing reference calibration data. We can also calibrate them individually upon request.

A dipole is narrow band, although if tuned manually, they can be used over a wide bandwidth. It can usually be tuned to particular frequencies, from 30 MHz to a maximum of 1 GHz.

Dipole antennas are usually constructed with two straight wires which are placed end-to-end on an identical axis, with the feed-line connected at both ends. In theory, this is the most straightforward dipole antenna you can build. This is slightly different to a Monopole antenna, which is constructed of a single wire/rod with one side of the feed-line connected to a ground plane.

To minimise RF interference during high frequency testing where the length of the dipole antenna and feed cables become unmatched – half wavelength dipole antennas use baluns between their coaxial cable and antenna. Baluns are used to re-balance power flows which are uneven. When the word is split; bal-un looks like 'balanced' and 'unbalanced'.

A Dipole antenna is often referred to as a reference antenna. These are the preferred antennas for field strength measurements associated with Open Area Test Sites (OATS), Normalised Site Attenuation (NSA) and most Semi-Anechoic Chamber calibrations.

Instead of using log-periodic antennas and biconical antennas for measuring EMI radiation – the dipole antenna is still the preferred instrument for conducting these tests. Although, half-wavelength dipole antennas are not widely used for sweep measurements because the individual tuning process at each frequency is very time-consuming. Check our Biconical antennas if you want a more efficient solution for making sweep measurements.

The dipole antenna was the earliest form of antenna and was pioneered by Heinrich Hertz in 1886 during the first German radio wave experiments.
