In this paper a novel compact wideband high rejection low-pass filter is presented. The low pass filter (LPF) consists of two hexagonal dumbbell shaped resonator placed perpendicular to each other. With such structure undesired harmonics are effectively suppressed with improvement in the stop band and sharpness factor. The proposed filter also has constant group delay within the rejection band. The new filter has compact configuration even better filter properties than the traditional filter. This design gives insight in designing a low-pass filter with reduced size of an arbitrarily shape. Using electromagnetic simulation software, it is shown that a compact LPF with 4.7GHz cutoff frequency and band reject of up to 16GHz has been successfully designed and simulated.
