1. Patented in 2004, one phased array antenna system is useful in automotive radar applications. 2. The Phased array antenna is fabricated at Bharat Electronics Limited ( BEL ), Ghaziabad. 3. Doppler is incompatible with most electronically steered phase-array antenna . 4. For example, a phased array antenna can send out a beam that is extremely thin. 5. Boeing began developing these phased-array antennas 16 years ago. 6. In wireless communication, space-division multiplexing is achieved with multiple antenna elements forming a phased array antenna . 7. Braun invented the phased array antenna in 1905. 8. Modern systems often used phased array antennas to allow rapid beam forming for highly accurate results. 9. Sterba curtains are modest-gain single-band curtain array antennas . 10. When used with a reflector to further improve the directionality, the result is a reflective array antenna .
