A Tuning Computation Technique for a Multiple-Antenna-Port and Multiple-User-Port Antenna Tuner

Figure 14

Reception patterns of the user ports, at 800 MHz, in the plane , versus the azimuth angle : the pattern of user port 1 is curve A; the pattern of user port 2 is curve B; the pattern of user port 3 is curve C; the pattern of user port 4 is curve D; and the average of curves A to D is curve E.
