Automotive MIMO Cellular Antenna Performance Comparison in an Over-The-Air Environment

This paper addresses the MIMO performance of automotive cellular antenna configurations as measured in an OTA (Over-The-Air) chamber. The OTA chamber measurement has been adopted by the cellular communications industry as a way to validate wireless devices such as smartphones, tablets and modems for RF compliance to the Carrier's network requirements. This performance assessment of an automotive cellular antenna in an OTA chamber is an approach to compare to wireless device performance and antenna verses antenna. The parameters that will be compared as a result of the OTA measurements are TRP (Total Radiated Power), TIS (Total Isotropic Sensitivity) and Data Throughput for given signal levels.
