Cumulative distribution estimates are presented for the one-second-average bit-error-rate (BER) which would be experienced on UHF links in a microcellular environment. It is assumed that users (subscribers) are moving at speeds ranging from quasi-sta

A propagation experiment has been designed and conducted at 900 MHz and 11 GHz to characterize microcell channels using various antennas at two distinct frequencies. It is found that propagation in rural areas is dominated by interference between the

The blockage effect of a large box truck passing through the line-of-sight path in a typical 11-GHz microcellular mobile communications link was measured. The results show that attenuation and diffraction effects can be significant when the truck is

A wide scan quasi-optical frequency diplexer is required for certain antenna applications. A waveguide array is a structure which can fill this requirement and also discriminate proximal frequencies. The wide scan characteristics are enhanced by tilt
