Design of a Microstrip Series Power Divider for Sequentially Rotated Nonuniform Antenna Array

International Journal of Antennas and Propagation, 2017
This paper deals with the design of a microstrip series power divider for circularly polarized sequential rotational antenna array. The theoretical description of the design is firstly proposed, comprising the cases of nonuniform weighted antenna arrays.
