Abstract
This paper describes compact antenna arrays for multiple input multiple output MIMO capacity studies in the HF band. These include a three-element receiver array with active electronics to provide broadband non-tuned operation across the entire HF band and a two-channel resonant magnetic loop array for transmitter applications capable of rapid tuning across greater than two octaves. MIMO measurements over a 255 km sky-wave link in the UK using these compact arrays and spatial arrays were performed to estimate the correlation coefficients between the different elements and the resulting MIMO capacity.
