Description

technical field [0001] The invention relates to the field of wireless mobile communication, in particular to a reconfigurable antenna with a planar end-fire pattern. Background technique [0002] An end-fire antenna is an antenna whose maximum radiation direction is parallel to the plane where the radiator is located. Common types of end-fire antennas include Yagi antennas and helical antennas. End-fire antennas have a wide range of application requirements in the military and civilian fields, especially in some scenarios with limited space size, such as handheld devices, cordless phones, vehicle and aircraft systems, etc., often need to be applied to low-profile end-fire antennas . On the other hand, the pattern reconfigurable antenna has the characteristic of dynamically controlling beam scanning, which can effectively reduce multipath fading and electromagnetic interference, and improve channel capacity. Therefore, low-profile, end-fire, pattern-reconfigurable antennas ...
