A microstrip array using high-directivity
Sierpinski fractal-inspired elements (under-sampled array)
needs less elements than an array using elements operating
at the fundamental mode (conventional array). Within the
same electrical area, both the under-sampled and the
conventional arrays present the same directivity. The
advantage of the under-sampled array is that as a less
number of elements is needed, it simplifies the feeding
network facilitating the integration of other microwave
components such as amplifiers, filters, and matching
networks for example. Previous research has been carried
out for under-sampled broadside array. In this paper,
scanning properties of the under-sampled array are
investigated.Peer ReviewedPostprint (published version
