A novel dual‐frequency shorted T‐shaped monopole antenna is proposed. The T‐shaped monopole is comprised of two horizontal arms of different lengths, which generate two separate resonant modes for the desired dual‐frequency operation, and one vertical arm is short‐circuited to a ground plane through an inverted‐L strip for good impedance matching. A prototype suited for WLAN operation in the 2.4‐ and 5‐GHz bands for a laptop as an internal antenna is constructed and tested. © 2004 Wiley Periodicals, Inc.
