2D Active Antenna Array Design for FD-MIMO System and Antenna Virtualization Techniques

Figure 4

FD-MIMO antenna panel measurements. The panel has 8 alternating polarization subarrays. (a) Simulated reflection coefficient magnitude for a single subarray. (b) Measured reflection coefficient magnitude for 8 subarrays within one FD-MIMO antenna panel. (c) Measured coupling coefficient magnitudes between adjacent subarrays in one panel. (d) Simulated co-pol and cross-pol radiation patterns of one subarray on azimuth () and elevation () planes at 2.6 GHz. (e) Corresponding measured radiation patterns.
