On the capacity analysis of compact space-multimode microstrip antenna arrays for IEEE802.11n MIMO-OFDM systems using sub-optimal MIMO detectors

The recent developments in wireless communication systems in indoor environments requires high data rate and high transmission quality especially for 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 receive for MIMO communication. In this work, the performance analysis in terms of spectral efficiency and data rate as well as compactness gain for compact multimode stacked circular microstrip patch antenna arrays (SCP-ULA) which are used for MIMO spatial-multiplexing communication in OFDM-WLAN systems conforming to IEEE 802.11n standard is presented by using linear MIMO detectors comparatively with respect to dipole antenna arrays (DP-ULA) and dominant-mode circular patch antenna arrays (CP-ULA).
