Computational and experimental analysis of highly isolated double side
triple band notched UWB MIMO antenna
Abstract
In this article, we present a double side highly isolated triple
band-notched UWB MIMO antenna for short-range wireless communication
applications. The proposed MIMO antenna design provides a UWB band with
the notched band at the IEEE INSAT C band satellite communication and
WLAN band (4.6–5.9 GHz), the X band uplink and downlink satellite
communication (7.70–8.43) and (10.3-10.98 GHz). It has double side
placement of polygon-shaped radiating elements, and an inverted L-shaped
stub to obtain high isolation between radiating elements. The proposed
antenna has a size of 18 × 28 mm2, which operates from 3 to 12 GHz. The
antenna characteristics such as isolation between radiating elements,
S11/S22, gain, and radiation characteristics are studied. The proposed
MIMO antenna has isolation of >19 dB, 0-7.5 dBi peak gain
and almost radiation pattern over the entire operating frequency band
with pattern diversity. Furthermore, MIMO diversity performance was
investigated using an ECC, diversity gain, multiplexing efficiency,
TARC, and CCL. The proposed UWB MIMO antenna has very low ECC of 0.0025,
and DG of >9.9, over the entire operating band (3-12 GHz).
Also, the real-time indoor short-range communication capability of the
proposed MIMO antenna demonstrated by using the NI 802.1 framework
