In this contribution, we present a linear array of 8 cavity-backed slots fed using a corporate feeding network realized by rectangular-waveguide cavities. The array has been designed to achieve a wide impedance matching bandwidth. To reduce the side lobe level (SLL), a non-uniform spacing technique has been applied for the array synthesis. The reported results show an impedance matching band (i.e., such that |S11| < -10 dB) of [9.76-12.71] GHz (≈26%) and SLL lower than -18 dB at the central operating frequency (11.5 GHz).

Abstract
In this contribution, we present a linear array of 8 cavity-backed slots fed using a corporate feeding network realized by rectangular-waveguide cavities. The array has been designed to achieve a wide impedance matching bandwidth. To reduce the side lobe level (SLL), a non-uniform spacing technique has been applied for the array synthesis. The reported results show an impedance matching band (i.e., such that |S11| < -10 dB) of [9.76-12.71] GHz (≈26%) and SLL lower than -18 dB at the central operating frequency (11.5 GHz).File in questo prodotto:
