Compact antenna covers immunity test standards

High performance dipole antenna for immunity measurements is optimised for broadband efficiency to support tests in the VHF range.

The R and S HK5000 is a high performance dipole antenna for immunity measurements that is optimised for broadband efficiency to support tests in the VHF range.

During immunity tests, subjects ranging from cars to mobile phones are exposed to high-strength fields to assess whether the interference impairs their functionality or, even worse, damages the equipment.

The antenna's compact and innovative design allows it to be set up at a distance of 1m from the device under test, in compliance with internationally accepted test standards.

The R and S HK5000 features especially low SWR values, leading to low internal reflection.

Therefore, the energy fed into the antenna is converted to radiated power with little loss.

The R and S HK5000 can be used to generate high field strengths - up to 200V/m and even higher - using generators with less power than would be necessary with conventional antennas.

The bandwidth of the R and S HK5000 can be used for transmission and reception applications in the frequency range from 20 to 100MHz.

The radiating elements are in the shape of a two-sheet hyperboloid and are mounted on a rotary shaft on a trolley.

The antenna's polarisation position is turned via remote control by means of a rotor that is also mounted on the trolley.

The R and S HK5000 broadband antenna is now available from Rohde and Schwarz.
