This paper presents a symmetric patterned defect introduced on the ground plane of a 2× 2 array of rectangular microstrip patches. A C-band design has been examined by removing nearly 50% metal from ground cladding which promises about 10 dB improvement in co-to-cross-polarized (XP) isolation over ±50° angular range around the boresight compared to a conventional geometry. A single unit has also been repeated in S-band for experimental studies indicating close corroboration with the simulated predictions. © 2018 IEEE.

Specially Designed Microstrip Array with Patterned Ground Plane for Improved Characteristics

2018 IEEE Indian Conference on Antennas and Propagation, InCAP 2018

Defected ground structure (DGS) integrated microstrip array has been explored and demonstrated here for the first time with the primary aim of achieving improved polarization purity. A shaped DGS with variable configuration has been conceived and designed for rectangular arrays. This unleashes new potential of DGS design by reducing the etched out area by 50%. A 2 × 2 DGS integrated array has been designed and experimentally demonstrated in X-band showing 12 dB improvement in the isolation between the copol and cross-pol radiations. © 2002-2011 IEEE.

Defected ground structure integrated microstrip array antenna for improved radiation properties

Defected ground structure (DGS)-integrated rectangular microstrip patch has been experimentally investigated with an aim to improve polarisation purity in radiated fields. Width to length ratio (aspect ratio) of a patch attributes different characteristic features. Therefore present experimental studies have been executed for four different aspect ratio values like 1.6, 1.3, 1.0 and 0.8. Folded defects have been employed in H-plane. Possibility of achieving high polarisation purity (over 25 dB isolation between co- to cross-polarised fields) with improved impedance bandwidth has been demonstrated. The variation in XP fields as a function of the patch aspect ratio has been investigated and a strong physical insight into the modal fields with and without DGS has been developed. © The Institution of Engineering and Technology 2014.
