A Fully Planar Feeding Network for Excitation of Series-Fed Dual-Polarized Antenna Arrays With Even Number of Radiating Elements

IEEE Access
This paper presents a method to design series-fed (SF) dual-polarized antenna arrays. The proposed antenna arrays consist of $nm$ radiating elements placed in $n \times m$ grid, where $n$ and $m$ are arbitrary even numbers.

Miniaturization design of a C-band low profile dual circularly polarized microstrip array antenna

四川大学学报. 自然科学版, 2023
This paper proposes a 5×5 miniaturized low-profile dual circularly polarized microstrip array antenna operating in C-band. Compared with conventional arrays, the element spacing is reduced by the interleaving of patches of adjacent 2×2 subarrays and the
