Design and development of a photonic bandgap (PBG)‐assisted shared‐aperture dual‐band orthogonal aperture‐fed rectangular microstrip patch antenna element, which is suitable for a portable very small aperture terminal (VSAT), are presented in this paper. The dual‐band dual‐polarized antenna element achieves 21% input impedance bandwidth at the S‐ and C‐bands. A comparison of the antenna with and without 2D PBG grids shows that the inclusion of PBG structures (PBGSs) improves the antenna performances. © 2005 Wiley Periodicals, Inc.
