Innovative integrated ferrite phased array technologies for EHF radar and communication applications

Ceramic-polymer ferroelectric materials for antenna applications

“…Electronically scanned microwave antennas are accomplished by electronically altering the phase across the antenna radiating aperture (by means of discrete phase shifting elements or by changing frequency). Conventional inertialess scanning techniques in the microwave region are not cheap[4,5, 61. A new scan antenna concept of realizable design using low-cost fabrication processes has been presented.A microstrip element which is often used is the rectangular resonator excited in the first order resonant mode.…”
