The LICEF antenna provides best performance in terms of gain, bandwidth adn differentiation of horizontal and vertical polarisation components of incoming microwaves. It consists of four probes implemented as pairs, which are rotated 90 degrees to each other so as to acquire the two different signal polarisations. Multi-layer 'microstrip' technology has been chosen for the circuit configuration. Each layer is dedicated to one polarisation. Each LICEF antenna weighs 190 g, is 165 mm in diameter and is 19 mm high.
