A small dual‐layer patch antenna designed for placement on a large conducting surface is presented. It uses the surrounding metal as a ground plane in order to reduce its size. The result is a small patch antenna with good radiation qualities in metallic surroundings. It can also be used in applications where shielding sensitive equipment from radiated fields is necessary, by using the shielding as the metal surface. It is constructed for use with the IEEE 802.15.4 standard at the 2.45 GHz ISM band. The lower layer is made in Fr‐4 with standard height and width. This makes eventual serial production cheaper. The antenna has a measured total efficiency between −1.5 dB and −3.6 dB in the frequency range it is designed for. The longest side is 18.35 mm, equaling 14.9% of the wavelength © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:723–727, 2013; View this article online at wileyonlinelibrary.com.
