Selection of the right horn for EMC susceptibility testing is never easy given the large

range of antennas on the market. This is further complicated by the fact that many

antennas experience loss of gain when working at close range yet the data given often

refers to far field conditions.

Q-par Angus have generated a set of charts that will enable the user to quickly select an

antenna from the frequency range and Volts / metre values required. These charts have

been calculated using our own in-house programs which take full account of any near

field effects. Further, in many cases the predicted results have been confirmed by

measurements. Thus the user can specify an antenna in complete confidence of its

performance.

Should amplifiers be required, a range of suitable products from TMD Technologies and

Bonn Elektronik GmbH are shown in a similar way.

EMC Antenna and AmplifierSelection Charts

Note: all power levels apply at the input of the antenna. However there is usually

enough reserve in the amplifier to overcome any small cable losses, though the user is

recommended to check this.

How to Select an Antenna and Amplifier

Contents

Antenna Selection Charts:

• 20 dBi Standard Gain Horns at 1 metre

• 20 dBi Standard Gain Horns at 3 metre

• Medium Gain Wide Band Horns at 1 metre

• Medium Gain Wide Band Horns at 3 metre

• HIRF range of antennas at 1 metre

TMD Technologies Ltd / Bonn Elektronik GmbH Amplifier Selection Charts

Worked example

Require 600 V/m between 0.4 and 1 GHz at

1 metre

From the antenna selection charts choose a

model that covers the frequency range

(WRD420 Quad Array)

Find a curve that exceeds the specification

(third one up)

Read off the power level required (1 kW)

From the amplifier chart select a model

based on frequency range and power (Bonn

BLWA4010-1000)
