In this paper, an orthogonal polarised dielectric resonator antenna (DRA) which can operate at S‐ and C‐band, has been designed as “shared‐element” for forming a dual‐band shared aperture array. Furthermore, in this shared aperture array, the S‐band array contains four shared‐elements, and the C‐band array contains four shared‐elements and twelve C‐band DRA elements. Moreover, a phase compensation power divider is employed to help offset the radiation performance differences between the two types of antenna elements when forming the C‐band array. A prototype array was fabricated and measured, showing that the antenna can cover the band of 2.4–2.63 GHz and 6.9–7.1 GHz, respectively. The isolation between bands is higher than 30 dB. The cross‐polarisation levels are less than ‐30 dB in both bands.
