Saffrine Kingsly,Malathi Kanagasabai,Mohammed Gulam Nabi Alsath,A.K. Shrivastav,Sangeetha Subbaraj,Yogeshwari Panneer Selvam,Ramprabhu Sivasamy,Yeragudipati Venkata Ramanarao +7 more
TL;DR: This letter presents the design and implementation of a compact microstrip filter with frequency and bandwidth (BW) reconfiguration that has simple geometry, low profile, and offers a higher level of operational flexibility in the designed frequency range.
Proceedings ArticleDOI
Formulation of size reduction technique in microstrip circuits by using DGS and DMS
TL;DR: In this paper, a simplified and accurate mathematical formula is derived to predict the reduced dimension of the microstrip circuit by using applicable etching geometry on plane of microstrip circuits such as DGS/DMS that will affect the resonance frequency of micro-strip circuit in desired direction due to increment of slow wave effect.
