摘要
An apparatus includes an antenna array having multiple antenna elements arranged in multiple sub-arrays. The antenna elements are arranged in at least two different types of sub-arrays. The at least two different types of sub-arrays have substantially orthogonal electric field (E-field) orientations. The antenna elements can be arranged in multiple patch sub-arrays and multiple substrate integrated waveguide (SIW) sub-arrays, and the patch sub-arrays can be interleaved with the SIW sub-arrays. Each patch sub-array can include at least two patch antenna elements coupled in series, and each SIW sub-array can include a conductive plate and multiple slots in the conductive plate. The SIW sub-arrays can resonate at substantially a same frequency as the patch sub-arrays.
