Order to achieve the same limit of coverage angle for both bands the design has to accept a large gain dip at boresight for the upper band performance. Of particular importance to a GNSS navigation beam is the group delay variation across the coverage zone, which can be calculated from the phase pattern in the coverage region at several frequencies within the operating band [5]. 7 for the low band of Galileo (see also [6]), calculated using a simulated radiation pattern, the result showing a total variation that will manifest as a pseudo-range error of around 30 mm across the coverage region [7].

Between the metallic layers is a lightweight foam spacer, and each coaxial feed point includes a capacitive gap to improve matching. 4 [3]. 2 Flight model of Galileo navigation antenna array. Taken from [1]; copyright EurAAP; used with permission. the signal transit time. The type A and B subarrays have their own beamformers and are fed by a central power divider (1:6) splitter with unequal arm lengths to implement sequential rotation [4] of the subarray feed elements (60◦ rotation and phase difference between adjacent subarrays).
