Coherence bandwidth characterisation for indoor mobile radio microcells at microwave and millimetre wave frequencies
… of indoor mobile radio microcells at 11 GHz and 62.4 GHz. Furthermore, the influence of the antennas radiation patterns and the effect of furniture on the value of the coherence bandwidth has been investigated.<br/><br/>A two branch frequency diversity system has been developed and used …

Measurements and modelling of reflection and transmission from smooth and rough surfaces at 62 GHz
… and the surface of various building materials at 62.4 GHz. Models have been applied to help in the interpretation of the reflectivity, scatter and transmissivity measurements performed on different materials.<br/><br/>Reflectivity and transmissivity measurements at 62.4 GHz have been made inside …

A discrete RET Model for Micro- and Millimetre Wave Propagation through Vegetation
… frequency bands, centered at 11.2, 20, 40 and 62.4 GHz frequencies.<br/><br/>The thesis provides a valid tested method to evaluate the dRET propagation parameters for various isolated volumes of vegetation. Such parameters, may subsequently be utilized into the proposed propagation model, which …

Radio Characterisation of Single Trees at Micro- and Millimetre Wave Frequencies
… frequencies, covering frequency band from 2 to 62.4 GHz, provided both model validation and a deeper insight into the problem. Single tree scatter has been shown to be modelled adequately in terms of a re-radiation function with parameters which can be deduced from measured data. This is an …
