Phased Array Antennas (PAAs) using patch-radiating elements are projected to transmit data at rates several orders of magnitude higher than currently offered with reflector-based systems.

However, there are a number of potential sources of degradation. The Iridium system will use active phased-array antennas using MMIC-based T/R modules at both L- and K-bands. Satellite-based personal communication services (SBPCS) will provide global communication with a common handset which will carry voice, paging, data, e-mail, fax, and video.

RF Microwave Wireless Systems tens or hundreds of TV channels, and many data links. The operating frequencies are in the gigahertz range. These phases are 0° (reference), °, 45°, and °. One major application of phase shifters is in phased-array antennas. Instead of operating in two states, on and off as in a switch, one can.

Data Stream | Antenna (Radio) | High Definition Television datastream. New devices and components for high frequency and millimeter wave integrated front-end receivers are being developed, active and low cost phased array antennas are being designed, and advanced software issues in coding, modulation, switching, and networking are being researched and developed.

Phased array antennas have traditionally used MMIC (Monolithic Microwave Integrated Circuit) phase shifters, which have two key weaknesses. They can contribute substantially to the cost of fabrication and tend to introduce a relatively high insertion loss, reducing the phased array antenna's effective EIRP (Effective Isotropic Radiated Power.
