A new non-reciprocal antenna array has been proposed in this paper for operation in microwave frequencies. The antenna array has been configured using a gyrator with the antenna patch elements through a T-type structure. Implementation of gyrator in the structure, that provides a phase shift of 180 degrees, results in a same beam direction of the forward and backward signals in the proposed antenna array. This proposed novel structure provides high radiation efficiency with beam steering and reduced side lobe levels.
