Description
Summary:This paper presents the design of a novel X-band half mode substrate integrated waveguide (HMSIW) bandpass filter by quarter wavelength resonators. The quarter wavelength resonators are coupled alternately by impedance and admittance inverters. Keeping the advantages of the substrate integrated waveguide (SIW), the proposed HMSIW filter is nearly half reduction in size. Simulated result shows the HMSIW filter has good performance of low insertion loss, compact size and high Q-factor.
