Abstract A novel ultra‐wideband (UWB) diversity monopole antenna printed on a personal computer memory card international association (PCMCIA) network card is presented. The antenna consists of two truncated square monopoles orthogonally and symmetrically printed on the two sides of a T‐shaped protruded ground plane, and is capable of operating in a very wide bandwidth, defined by a 10‐dB return loss, of about 5.4 GHz (about 2.3–7.7 GHz). In addition, across the operating bandwidth, the antenna also shows good port isolation ( S 21 < −20 dB) and can provide spatial diversity for the obtained radiation patterns of the two truncated square monopoles which substantially cover complementary space regions. © 2003 Wiley Periodicals, Inc.
