A new design of broadband semi bow‐tie quasi self‐complementary (QSC) CPW series‐fed array antenna for C‐band application is presented and discussed. To realize the presented array element, miniature quasi‐self‐complementary antenna element with a coplanar CPW‐like matching technique is utilized. The proposed element provides a wide impedance bandwidth from 3.95 to 11.25 GHZ for S 11 <−10 dB. The QSC array antenna's operation is additionally enhanced with assembling of four elements that is designed, using symmetric CPW‐fed with matching method. The measured results illustrate impedance bandwidth from 4.25 to 9.9 GHz for VSWR < 2. The feed‐line is tapered at input section between series‐fed network and antenna because of optimum input impedance matching that leads to improve impedance bandwidth. The measured results of the proposed array also exhibit relatively good radiating pattern and gain values. The design process and the experimental results are discussed in details. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:95–98, 2017
