However, the easiest way to get started is to simply use our Excel antenna array spacing calculator `Antenna_Array_Size_Calculator.xlsx` available on this repo at https://github.com/krakenrf/krakensdr_docs/tree/main/antenna_array -# Using the Excel Calculator -In the Excel calculator yellow boxes indicate numbers you can change. - -## Spacing Multiplier Explained +# Spacing Multiplier Explained Both the spacing multiplier and frequency determine array sizing. The spacing multiplier is a value that is multiplied against the wavelength of interest resulting in the 'interelement spacing' of the array. The interelement spacing is the distance between each element in the array. In all situations the spacing multiplier must be kept under 0.5 to avoid ambiguities (more than one possible bearing solution). Ideally, you also want to keep the spacing multiplier above around 0.2. The larger the spacing multiplier the greater the resolving resolution of the array. This means better multipath handling. Below 0.2 the resolution becomes too poor. + + +# Using the Excel Calculator +In the Excel calculator yellow boxes indicate numbers you can change. + ## Frequency to Array Radius Enter your frequency here, and it will show you the antenna radius for that particular frequency, for a range of spacing multipliers. |
