$V$ -Band High-Gain Printed Quasi-Parabolic Reflector Antenna With Beam-Steering

A novel design of printed V-band quasi-parabolic reflector antenna is discussed. Two possible excitation methods are proposed which are used subsequently to design a more complex antenna with beam-steering capability. The radiation performance of the designed antenna is studied using full-wave simulations based on the finite-element method. The simulation results are verified experimentally.
