Antenna Array Directivity Maximization With Sidelobe Level Constraints Using Convex Optimization
IEEE Transactions on Antennas and Propagation, 2021New methods for maximizing the directivities of the array antennas are proposed. First, the array pencil beam (PB) directivity maximization problems without or with sidelobe constraints are formulated as convex optimization problems, which are solved ...

Synthesis of Irregular Phased Arrays Subject to Constraint on Directivity via Convex Optimization
IEEE Transactions on Antennas and Propagation, 2021The synthesis of irregular phased arrays subject to constraint on directivity is fulfilled by convex optimization. In particular, based on the membership between the antenna elements and subarrays, the dictionary matrix, the resulting sparse excitation ...
