 How Big Is A Wavelength?

In a phased array system, some of the most important design considerations are the number of elements and the element spacing since both drive cost and performance. In traditional arrays an inter element spacing of less than half the wavelength (<λ><λ/2) is required to mitigate grating lobes. To understand the shift in system design this brings about, this paper looks at the physical scale of different wavelengths compared to some familiar references.
