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

Abstract EN

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.

A more flexible open octagon shape instead of the classical open ring is suggested, highlighting benefits in the case of nonuniform power distribution.

A design example of an ultra-high frequency (UHF) band 4×4 sequentially rotated Tschebischeff antenna array finally demonstrates the effectiveness of the proposed implementation.
