A Compact Quad-Port UWB MIMO Antenna With Improved Isolation Using a Novel Mesh-Like Decoupling Structure and Unique DGS

Praveen Kumar et al.

Summary: This paper presents a design of an ultrawideband (UWB) and four-port MIMO antenna. The antenna structure is modified to achieve a broader bandwidth by including guitar shape slots on the radiator and a half-circle slot in the lowered ground plane. The mutual coupling in the MIMO elements is minimized by parasitic elements and a mesh-like structure, improving isolation.

Design of a Six-Port Compact UWB MIMO Antenna With a Distinctive DGS for Improved Isolation

Praveen Kumar et al.

Summary: This paper analyzes a low-profile printed six-port ultrawideband (UWB) antenna with a novel decoupling structure for enhancing port-to-port isolation. The proposed design utilizes symmetrical pyramidal form UWB antennas and defective ground structures as a unique decoupling structure, resulting in a below -10 dB impedance bandwidth of 116% and a peak gain of 8.3 dBi. The design also meets the requirements for MIMO applications in terms of time domain characteristics and diversity metrics.
