Two new types of compact ultra-wideband antennas for EMC measurements

摘要

We present two new types of ultra-wideband antennas for EMC measurements: the Eleven antenna and the self-grounded antenna. Both antennas have a compact size and can have multiple ports for flexibility in measurement tests. The radiation patterns of the antennas can be directional or of multi-beam. The antennas have a low manufacture cost and light weight, easy for installation, which is especially important for low frequency antennas.
