The recent developments in wireless communication systems in indoor environments require high data rates and high transmission qualities especially for the support of multimedia applications in WLAN (Wireless Local Area Network) systems. In the next-generation communication systems, the spectral efficiency and transmission quality can be vastly enhanced by using compact multiple-antennas with low correlation ports at both the transmitter and the receiver for MIMO communications. In this paper, the performance analysis in terms of spectral efficiency, data rate and compactness gain for compact multimode stacked circular microstrip patch antenna arrays (SCP-ULA) which are used for MIMO spatial-multiplexing in MIMO-OFDM WLAN systems conforming to IEEE 802.11n standard is presented by using low-complexity linear MIMO detectors with respect to dipole antenna arrays (DP-ULA) and dominant-mode circular patch antenna arrays (CP-ULA).
