Abstract
A compact, stacked, multi-frequency dipole antenna array is designed and presented for use in Multiple Input Multiple Output (MIMO) wireless communication systems. The array consists of two dual band frame-printed dipoles occupying the same physical space. Each antenna can operate in the 2.4 and 5 GHz bands for wireless local area network (WLAN) applications. The array can be used in a 2 2 MIMO link at either the transmitter (TX) or receiver (RX) or both. The lack of spatial diversity that arises from having co-located antennas is counterbalanced by the pattern diversity resulting from the mutual coupling between the two antenna elements. This system takes advantage of the otherwise undesirable mutual coupling within the antenna array elements by producing pattern diversity from the shift in the radiation patterns. The proposed antenna array was simulated and manufactured and its radiation characteristics were tested. Channel measurements were also taken using the antenna array and the WARP software defined radio platform. The proposed antenna array has radiation characteristics and measured channel capacity comparable to that of specialized antennas operating in each of the frequency bands, while providing the added benefit of size reduction.
