The array of multiple quasi-coherent millimeter wave (mm-wave) sources can reduce speckle by destroying coherence and is only effective when a very large surface (typically 1.5m by 1.5m) is filled with thousands of expensive mm-wave sources. This virtually exists till to now in the mm-wave range as it is unexpectedly expensive. Angle diversity technique using multiple antenna beams to receive multipath signals arriving at different angles can be used to reduce speckle. In this work such multi beam array is realized by using a single mm-wave source, BWO and a meta-material array where each element works like a digital 'ON' and 'OFF' switch by changing frequency.
