Abstract A balance‐fed T‐monopole printed antenna is newly proposed in this letter for modern mobile applications. This T‐monopole antenna is for stripline‐feeding with balanced signals. The antenna is compact and has the particular merit of immunity to the influence of size variation in feed ground. A prototype of the antenna for operating at the universal mobile telecommunication system (UMTS) band has been constructed and is shown as an example. Its return loss and radiation patterns have been simulated and measured. The experimental results demonstrate the broad bandwidth and omnidirectional radiation characteristics of the newly developed antenna, as well as the merits summarized here. © 2007 Wiley Periodicals, Inc.
