Simulated and measured A-SBFA performance. a Comparison of measured and simulated directivity versus frequency with frequency bands of interest indicated. b Simulated and measured S11 of A-SBFA with impedance matching network. c Comparison of simulated and measured A-SBFA gain at L2 (E-plane cut). Both the co-polarized (V-pol) and cross-polarized (H-pol) gain patterns are shown. The E-plane is the y–z plane in Fig. 1a. d Comparison of simulated and measured A-SBFA gain at L2 (H-plane cut). The H-plane is the x–z plane in Fig. 1a. e Comparison of simulated and measured A-SBFA gain at L1 (E-plane cut). f Comparison of simulated and measured A-SBFA gain at L1 (H-plane cut)
