This paper presents the design, simulation and test results of a novel photonic band‐gap (PBG) structure for filter application. The proposed PBG structure is a 50Ω meander microstrip line with a single rectangular ground‐etched pattern instead of conventional periodic ground‐etched pattern. The simulated results, verified by the test results, demonstrate that this proposed structure provides less ripple in the lower pass‐band with an increased rejection bandwidth of about 20%, as compared to a conventional PBG filter with same fill‐factor. This single etched ground pattern enables easier fabrication and packaging, as compared to conventional multiple ground‐etched patterns. © Wiley Periodicals, Inc.
