A novel series‐fed microstrip array antenna with a miniaturized feeding network suitable for wireless local area network (WLAN) and radio frequency identification (RFID) applications is presented.This array works with 10 patch elements and utilizes artificial transmission lines (ATL) to design the feeding network to well reduce the whole size. Compared to conventional series‐fed array designs, the proposed array can achieve not only a small size of merely 14 ( L ) × 230 ( W ) mm 2 but also a wide operating bandwidth from 5 to 5.94 GHz. Experimental results exhibit that fairly good broadside radiation pattern with adequate half‐power beamwidth for practical application can be obtained with our array design. Therefore, the proposed microstrip array antenna with a compact size is well suitable to be integrated within the WLAN/RFID systems as a transmitting antenna. © 2011 Wiley Periodicals, Inc.
