The study compares two designs of antenna units in terms of reducing the coupling ratio between the transmitting and receiving antennas. The first design is the original transceiver antenna unit of an electronic countermeasure aircraft, which contains two transmitter antennas close to each other in a shared compartment and a receiver antenna in a separate compartment behind a solid screen with bevelled edges. The second design is an upgraded antenna unit of a compact electronic countermeasure station, in which each antenna is located in its own compartment formed by a cross-shaped divider; additional measures have also been taken to improve the modulus of the coupling ratio between antennas. Both antenna unit designs use the same broadband Vivaldi antennas.
