This article presents a tag antenna for radio frequency identification (RFID)‐based wireless structural health monitoring systems. An ultra‐high frequency (UHF) microstrip patch tag antenna is designed with a new generation RFID tag chip for the Australian UHF RFID frequency band. Simulation studies with optimized slits demonstrate the ability of the antenna to tolerate the influence of construction materials such as concrete and metal on its resonant frequency, maximum gain, and read range. Noncontact measurement of the resonant frequency and experimental verification of the maximum gain of the fabricated tag antenna show good agreement with simulated performance. Read range measurements are conducted to verify the performance of the tag antenna on metal structures. It is also shown that the proposed tag antenna can be easily modified to operate in other UHF RFID frequency bands. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2231–2237, 2016
