A Switchable Biomimetic Antenna Array [PDF]
IEEE Antennas and Wireless Propagation Letters, 2021 Biomimetic antenna arrays inspired by the fly Ormia ochracea showed a promising improvement of the angle estimation capabilities of radar sensors. So far, there is usually a loss of output power associated with this improvement decreasing the detectability of weak radar targets. In this paper, an electronically switchable two-element biomimetic antenna
