1. Introduction

The MIMO communication system has been one of the most promising technologies, well suited

for high data rate communication. A MIMO (Multiple-Input-Multiple-Output) system use at least

two antenna structures and is more advantageous than single-input single-output (SISO) in an

aspect of increasing channel capacity and reducing transmitting power. MIMO antennas should

have compact structure, high radiation efficiency, low envelope correlation, and high isolation

between the signal ports.

In small structures (antennas spaced closely), the application of MIMO technology has been

restricted by high degree of coupling and spatial correlation between antenna elements due to

the limited available space. The isolation between antennas become critical as it can deteriorate

the system performance and decreases channel capacity.

The Hercules MA.510 MIMO antenna is low profile, heavy-duty, fully IP67 waterproof external

M2M antenna for use, transportation and remote monitoring applications. This unique

omnidirectional antenna provide high efficiency and high isolation between antennas elements

in a heavy-duty low profile compact structure, delivering powerful MIMO antenna technology for

Wi-Fi 802.11n and emerging 802.11ac.

The antenna screws down permanently onto a roof or metal panel and can be pole or wall-

mounted. One antenna elements is vertically polarized and one is horizontally polarized to

increase the isolation between antennas.

For industries such as remote monitoring, smart meter systems, construction equipment, public

safety at only 29mm high, the Hercules MA.510 MIMO antenna provides an unobtrusive, robust,

rugged antenna that is durable even in extreme environments.
