Measurements on indoor channel characteristics using wideband MIMO antennas

Abstract

In this paper, we design two wideband compact MIMO antennas, and utilize them for experiments on indoor channel characteristic measurements. One of the antennas is a three-port orthogonally polarized, and the other is a six-port formed into a cube. The antennas operate at center frequency of 2.6 GHz and support a bandwidth of over 400 MHz. Isolation between the ports of the antennas are kept under -18 dB. Using these antennas, we measure the channel characteristics of the indoor environment, and analyze the performance of the antennas. As a result, high data rate capacity can be achieved with the proposed compact antennas, making them applicable in MIMO wireless communications.
