A compact, one‐piece, metal‐plate, multiple antenna system capable of generating concurrent 2.4‐ and 5‐GHz bands with directional radiation patterns for wireless local area network (WLAN) applications is presented.The design is obtained by integrating two loop and two slot antennas arranged sequentially along a rectangular antenna ground into a single flat plate with overall size of 3 × 75 × 75 mm 3 . The ground plane in this design not only acts like a reflector for the 2.4 GHz loops but also provides the 5 GHz slots an efficient finite ground to properly excite the antenna. With a simple structure, compact size, and good radiation characteristics, the antenna is easy to fabricate and suitable for applications in WLAN access points. © 2012 Wiley Periodicals, Inc.
