A planar monopole UWB antennas with rounded patch and ground plane possessing improved impedance matching

A planar monopole UWB antenna with rounded patch and rounded truncated ground plane for ultra‐wideband applications is investigated. The geometry of the antenna is optimized to obtain a minimum return loss. The antenna provides the return loss better than −15 dB in almost the entire (3.1–10.6) GHz frequency band and good radiation characteristics. The simulated and experimental results are in a good agreement. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 54:335–338, 2012; View this article online at wileyonlinelibrary.com.
