Distributions of EVM for a transmitting antenna operating in different modes. The three curves in a, b, and c were measured along the whole path when only one element was excited at a time (without switching). The curve in d was measured when the antenna was operated in the mode of automatic switching in terms of trigger distance. e Lower envelope of EVM of the curves in a, b, and c in zone 1. f\ Lower envelope of EVM of the three curves in a, b, and c in zone 3
