Rohde & Schwarz has introduced a dipole antenna that provides high performance for immunity measurements.
To support these tests in the VHF range, the HK5000 is optimised for broadband efficiency. During these tests, automobiles are exposed to high field strength to measure whether the field strength impairs their functionality or 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. This complies with international test standards.
The R&S HK5000 features especially low standing wave ratio (SWR) values, thus low internal reflection. This means the energy fed into the antenna is converted to radiated power with low loss. The R&S HK5000 makes it possible to generate high field strengths of up to 200V/m or more.
The bandwidth of the R&S HK5000 can be used for transmission and reception applications in the frequency range from 20MHz to 100MHz. The actual radiators are in the shape of a two-sheet hyperboloid and are mounted on a rotary shaft on a trolley.
