Abstract
A method and system of merging signals feeding the antenna elements by using a combiner network and to create an antenna reference point representing the signal representation in the air. This merged signal will be easily accessed for measurement purposes. An additional signal combiner connected to the output terminals of the distributed power amplifier modules of the active antenna creates a measured virtual antenna reference point which may be utilized in testing and typing active antennas having distributed electronics for a certification according to standards for GSM, PDC and DCS. The corresponding method for measuring active receive antennas is also disclosed. Also discloses a measurement system for application of the new method of obtaining a virtual transmit or receive antenna.
