Dual-band antenna pair for MIMO WiFi compact mobile terminals

In this paper a compact dual-band WiFi antenna pair is proposed which is suitable for compact mobile terminals such as smart phones. The proposed antenna pair is wrapped on a 20.8×3.3×2.7 mm³ spacer and is located at the edge of a 122×62 mm² ground plane. The antenna geometry advantage is that it allows mobile phone manufacturers to accommodate four antenna elements for Multiple-Input Multiple-Output (MIMO) WiFi applications in their products. Apart from antenna characterization, channel capacity of the proposed antennas is also provided.
