Measuring Multi-Antenna Isolation Using A Multiport VNA

Higher densities of Radio Frequency (RF) transmitter and receiver antennas on many platforms is a result of the expansion of wireless technology. A single platform such as an automobile, police car, airplane or military platform can result in numerous antennas closely located by each other. Knowing the actual antenna to antenna isolation allows engineers to assess the filtering requirements in wireless receivers. This also allows engineers to mitigate Cosite Interference issues at the Platform Level and in System Integration. Download the full application note for more information.
