Diversity is a required property for antennas in Multiple Input-Multiple Output (MIMO) systems. In this paper a pattern diversity antenna is presented for operation in the 2.4 band of IEEE 802.11n WLAN MIMO standard. This compact antenna is formed by two shorted air substrate patch antennas located back to back in order to produce two lobes oriented in different directions. Input matching is done...
Search for antennas to meet more complex requirements for new wireless technologies is a continuous industrial and academia activity. Two dual antennas in compact array for MIMO applications are presented in this paper. An air substrate patch antenna is used in combination with a quarter wavelength monopole, and with a small inverted L monopole to form two compact arrays of antennas. These all conductor...
