This paper represents the compact metamaterial inspired triple-band filter using two inverted S-shape resonator and two C-shape stub with via. Proposed filter is printed on FR-4 epoxy glass substrate with 1.6 mm thickness. The measured 3 dB fractional bandwidth of 40 % (1.6-2.4 GHz), 16.5 % (3.9-4.6 GHz) and 14.3 % (5.2-6.0 GHz) at centre frequencies 2.0 GHz, 4.25 GHz and 5.6 GHz respectively. This filter offers electrical circuit size of 0.22λg × 0.16λg, where given λg is the guided wavelength at centre frequency of first passband 2.0 GHz. The performance parameter of designed filter have characterized by fractional bandwidth, insertion loss, dielectric constant, return loss, circuit size and group delay. Both simulated and measured results are shown to validate the proposed filter. Finally, the MTM properties of proposed filter has been verified by extracting its dispersion diagram. It is suitable for GSM 1800, LTE 2300 and WiMAX (5.2-5.8 GHz) application.
