This article presents the design of a novel structure to increase bandwidth of single layer dual‐polarized microstrip patch antenna using metallic cone on top of the patch antenna. The antenna is fed by two orthogonal 50Ω microstrip feedlines using λg/4 transformers. Tunable stubs are employed along the quarter‐wavelength transformer to optimize the antenna's impedance match. Results confirm the parasitic cone mounting provides significant bandwidth enhancement. The antenna was fabricated, and a good agreement is achieved between measurement and simulation. The measured results show that the antenna achieves a −10 dB impedance bandwidth of 29% and isolation of >22 dB between the two input ports across its operating bandwidth (4.8–6.44 GHz) with low cross polarization level of <20 dB. © 2016 Wiley Periodicals, Inc.
