The antenna is the transmitter or receiver part of the system that emits electromagnetic waves into space or receives energy from electromagnetic waves. Antenna is a converter, because the antenna emits the electrical energy it draws from the circuit as EM energy into space (or vice versa). Antennas can be used as a transmitter and receiver.

EMC engineers are intertwined with antennas every day. They perform emission measurements and immunity tests every day in an anechoic chamber and / or outdoors.

The emissions caused by the tested device / product in the worst case are taken with the help of the receiver antenna. It is recorded in the EMI receiver. The recorded values ​​are compared with the limit values ​​specified in the standards. The main problem here is to establish a healthy relationship between the voltage recorded in the EMI receiver and the emission caused by the product. In order to do this, it is imperative to know the effects of all factors from the receiver antenna to the EMI receiver numerically.

In immunity tests, the product is resistant to strong electrical and magnetic fields, fast transients, electrostatic discharge (ESD) and voltage fluctuations (surges, voltage dips).

EMC antennas are used in RE measurements to record unwanted device emissions. RS tests are used to create a high power homogeneous electric field in the device position. RE measurements are made with calibrated antennas. In immunity tests, the antenna’s calibration is not important. The important thing is to create a high-power homogeneous field.



Biconical antenna is used for emission and immunity tests.It usually has a frequency range from 25MHz to 300MHz. It can be used as a transmitting or receiving antenna. It has frequency range of 25 MHz to 300 MHz.


Log Periodic Antenna is used for EMI radiated emissions or immunity tests.  Our Log Periodic Antenna can be used inside an anechoic chamber or outdoors in an open area test site. It has frequency range of 300 MHz to 1 GHz.


Horn Antenna is used for radiated emissions or immunity tests.  Most EMI test standards require the use of horn antenna for testing above 700 MHz. It has frequency range of 700 MHz to 18 GHz.


Combilog antenna is for EMC emission and immunity up to 2 GHz. It combines the electrical properties of two antenna (biconical and Log ).  It reduces overall testing time by 20 – 30% due to antenna switching.


Dipole antenna used to transmit and receive a fixed frequency signal. The dipole antenna has a frequency intermittently, adjusting the length of the elements on each side of the antenna to the half-wavelength of this frequency. Dipole antenna used to transmit and receive a fixed frequency signal. This is an antenna that complies with EMC standards. It has frequency range of 30 MHz to 1 GHz.


 Active loop antenna is ideal for emissions measurements. It has frequency range of 9kHz to 30 MHz.
