Abstract

A novel multi-band printed antenna, ideal for all IEEE 802.11 wireless local area network (WLAN) systems, is presented. It operates well in all frequency bands (2.45, 4.9, 5.25 and 5.775 GHz) allocated worldwide for IEEE 802.1 1a, b, g and j wireless computer systems, demonstrating a return loss >10 dB, an excellent efficiency and a wide radiation pattern. The antenna is printed on a thin (0.8 mm), low cost substrate FR4 using standard microstrip fabrication techniques at a very low cost, and hence it does not require extra processes for mounting or connecting it to the transceiver board. Its very small footprint area (only 10×10 mm) makes it the smallest quad-band WLAN antenna available yet. The antenna is based on a unique layout of two bent printed strips in which one strip bends around the other and their terminal segments are closer to each other than the rest.
