I have a question on measuring gain/efficiency. We use antennas in a plastic housing, and we would like to see how different changes affect the gain/efficiency of the antenna.
Currently all we have is an Agilent 8714ET 2-port Vector Network Analyzer, which we use to measure the VSWR. Is there a way to use the 8714ET to measure gain/efficiency? What other equipment would we need to get?
Any suggestions would be appreciated.
