Pattern-Reconfigurable Water Horn Antenna
IEEE Transactions on Antennas and Propagation, 2021 A novel horn antenna is reported in this communication, which is realized by using water walls instead of traditional metallic walls. Due to its fluidity, water filling different channels can be readily controlled. Therefore, the proposed water horn antenna can operate in two states: H-plane horn state and leaky-wave state, resulting in different ...
