Abstract The article presents the design of a compact hepta-band antenna for portable and embedded applications targeting the GSM-900/DCS/PCS/UMTS-2100 cellular and 2.4/5.2/5.5-GHz WLAN bands. A printed inverted-F antenna with a folded primary arm and a second radiating arm on the bottom surface of the substrate initially provides tri-band operation in the 900, 1700, and 2450-MHz bands. The shorting-arm is relocated below the primary arm for a reduction in occupied area. The addition of a long slot in the ground plane offers an additional operation around 2100 MHz, bridging the 1700- and 2450-MHz resonances and promoting significantly wide-band performance of more than 900 MHz in that band. A second ground slot allows the antenna to support two of the 5-GHz WLAN bands. Laboratory measurements confirm the performance of the final hepta-band antenna, with 6-dB return loss met from 880–1000, 1680–2590, and 5150–5710 MHz, and better than 10-dB return loss at the centers and edges of these bands.
