Currently, antenna technology is developing to a full digital array structure from the previous active phase array antenna. Thus far, it has been challenging to build a full digital array antenna, because making a small transceiver with an analog digital converter for each array element has technical limitations in semiconductor devices. However, it is now possible to fabricate a digital TR-module having a transceiver and analog digital converter for each element in the L-band. In this thesis, the results of the L-band digital TR-module and alignment method for a full digital array structure are presented to verify the possibility of a digital active array antenna. Transmitting beam and receiving multi-beam measurements were performed, which proved the free beam-forming function of the full digital array. [ABSTRACT FROM AUTHOR] |
