Smart multibeam phased array antenna for GSM, GPRS and EDGE

Paratek Microwave, Inc. developed a multibeam phased array antenna system at 1.8 GHz, suitable for application as a smart GSM base station antenna. The antenna is also capable of handling GPRS and EDGE extensions to the basic GSM system. The antenna array elements are phased using phase shifters based on Parasca/spl trade/ voltage tunable materials. An antenna system overview and a description of the basic operation will be given, followed by system simulation and pattern measurement results.
