Abstract:
The transmission characteristics of a high frequency circulator using coplanar wave guide have been designed and studied. To miniaturize the device, we have dramatically reduced the thickness of the YIG ferrite layer (Yttrium Iron Garnet). The circulator has an hexagonal shape with dimensions of 10*10 mm2, the width of the central line (LINE) is 400 ?m, the space between LINE-to-GND is 130 ?m and the thickness of ferrite film (YIG) is 10 ?m. this compact circulator operates at 10 GHz. The insertion loss is 3.14 dB, the return loss is 18.57 dB and the isolation is greater than 20 dB.
