Progress In Electromagnetics Research C, 2010 In this work, the introduction of Defected Microstrip Structures and Defected Ground Structures is presented to improve the performance of a traditional stepped-impedance microstrip lowpass fllter. The attenuation in the stop-band is enhanced by more than 15dB and selectivity is increased, without modifying the insertion loss in the pass band.

Variations of Compact Rectangular Microstrip Antennas Using Defected Ground Plane Structure [PDF]
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2022 The defects in the form of slots have been employed in microstrip antenna either on the patch or the ground plane to yield frequency reduction. However, the reported work does not provide any comparative study that highlight upon the frequency and cross ...
