MINIATURIZED MICROSTRIP PATCH ANTENNA WITH DEFECTED GROUND STRUCTURE [PDF]
Progress In Electromagnetics Research C, 2014 The aim of this work is to miniaturize a microstrip patch antenna resonating at 3 GHz. For this purpose, defected ground structure (DGS) has been employed to shift the resonance frequency of an initial microstrip antenna from 5.7 GHz to 3 GHz by disturbing the antenna's current distribution.

A Defected Ground Structure Based on Matryoshka Geometry
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2022 Abstract A Defected Ground Structure, DGS, based on matryoshka geometry is described in this paper. The proposed DGS geometry is outlined and initial design equations are presented. Four prototypes, with resonant frequencies 2.17 GHz, 2.44 GHz, 2.99 GHz and 3.73 GHz, were designed, fabricated and characterized, observing a good agreement between ...

International Journal of Antennas and Propagation, 2020 Suppressing higher-order modes up to sixth harmonics of the fundamental working frequency in a single-layer microstrip line-fed patch antenna has been successfully demonstrated. Higher-order modes of the antenna are suppressed by simultaneously employing
