| Abstract: | Several new designs are presented for coplanar waveguide (CPW) open- and short-ended shunt stubs patterned on the centre conductor. Unlike conventional stubs which are patterned on the ground plane, the new designs are more compact and less radiative. They also provide more flexibility to the design of CPW circuits. The performance of the new stubs is verified by experiment and simulation and is found to be very satisfactory over the large frequency band 0–50GHz. Experimental results obtained for a conventional and new stub show that the new stub is less radiative. |
