Abstract In this paper, a dual linearly polarized stacked array for ISM band base station applications is presented. The patches on the bottom layer are fed diagonally by a microstrip line. A superstrate layer is stacked above the bottom layer to increase the operating bandwidth. The design parameters are simulated and optimized for the satisfactory impedance and radiation characteristics, which are compared against measured results. The measurements show that the antenna satisfies the requirements for a base station antenna and is capable of having broad bandwidth for the VSWR ≤ 1.5 with stable radiation patterns, low front‐to‐back ratios, and side‐lobe levels in the planes of interest. © 2003 Wiley Periodicals, Inc.
