Design parameters of the directivity tuner and simulated directivity variations using the design parameters sweep from −10% to +10% from the optimized values (L = 36 nH, CLS = 132 pF, CLP = 8.2 pF, RL = 97 Ω, RR = 54 Ω, CRP = 1 pF, and CRS = 24 pF). (a) L, (b) CRP and CRS, (c) RR and RL, and (d) CLP and CLS.
