A low-profile dual-band MIMO antenna design and measurement with AMC reflector

Abstract

MIMO is a method which uses a number of antennas as a receiver and a transmitter, and increases the capacity of the wireless channel because it transmits parallel information in an environment that is full of multipath effects by avoiding the need for extra power and bandwidth. We suggest a low-profile, dual-band (2.4-5.8 GHz) Multiple-Input Multiple-Output antenna; and use two identical L-shaped antennas that have high isolation. The dual-band Multiple-Input Multiple-Output antenna consists of a compact size of 82.50 x 40.0 mm(2). The parameters of the antenna (s(11), s(21)) are measured by employing the FieldFox Network Analyzer. The dual-band MIMO antenna that has high isolation and that uses an Artificial Magnetic Conductor (AMC) is dealt with in the present manuscript. The computed loss of return is -21 dB for 2.4 GHz, and 12 dB for 5.8 GHz.
