Abstract
This paper proposes the integration of a dual-band bandpass filter and antenna using a filter synthesis method. A dual-mode perturbed patch resonator and a dual-mode patch antenna are used in the implementation. The two patches are placed back-to-back to share a common ground. To increase the degree of freedom in controlling the channel bandwidths and to avoid radiation interference, a slot coupling technique is used to couple both patches. The patch resonator performs the signal splitting and combining function while the patch antenna contributes to the filtering poles and performs the radiating function. Good agreements have been achieved between the measurements of the prototype device and the simulations.
