2.6.2.1 RX Antenna Element Performance
Simulated RX antenna performance from RX Array A is shown below. Three different RX antenna were excerpted to show the overall performance across the array. These excerpted antenna are labeled RX1, RX4 and RX8 shown. This selection is meant to highlight behavior of the RX antenna near the edge of the RX antenna rrays and near the center of the arrays. Due to coupling between antenna, the performance near the edge of the array changes from the performance near the center of the array.
