Abstract :
Experimental results are presented for a microstrip below-surface circulator which indicates that it can have a comparable performance to conventional types, and can thus be used to form a low-cost device suitable for use in thick-film MICs. Simple design expressions for the surface circulator based on quasistatic estimates are also presented.
