Circularly polarised MIMO tapered slot antenna array for C-band application

A novel configuration of a multiple-input multiple-output (MIMO) circularly polarised (CP) antenna array operating in the C-band is presented. The array consists of 2 × 2 antipodal tapered slot antenna elements created in the sides of a rectangular as the rectangular grid that supplies a broadband i...

Zusammenfassung:	A novel configuration of a multiple-input multiple-output (MIMO) circularly polarised (CP) antenna array operating in the C-band is presented. The array consists of 2 × 2 antipodal tapered slot antenna elements created in the sides of a rectangular as the rectangular grid that supplies a broadband impedance bandwidth and high gain array. To provide broadband MIMO with polarisation diversity, the antenna uses a dual-port feed network consisting of couplers, a crossover and delay lines which the diversity of polarisation changed by input ports.
