Harmonic Suppression Characteristic of a CPW-Fed Circular Slot Antenna Using Single Slot on a Ground Conductor

By Junho Yeo and Dongho Kim
Progress In Electromagnetics Research Letters, Vol. 11, 11-19, 2009


A CPW-fed circular slot antenna with a slot on a ground conductor is presented for harmonic suppression. The antenna has a multi-band rejection characteristic where the second and higher rejection bands are integer-multiple of the first band, and this is generated by inserting single slot on a ground conductor of the antenna. Good agreement between the simulated and measured results is reported and the integer-multiple notch bands can be adjustable by changing the length of the slot on the ground plane.
