Abstract A very‐low‐profile, 2.4/5‐GHz monopole antenna well suited for large screen‐to‐body‐ratio notebook computers with an ultra‐thin bezel for wireless local area network (WLAN) applications is presented. The antenna height was 4 mm only, and the design was constructed on a low‐cost dielectric substrate of size 4 mm × 30 mm to be easily placed within the ultra‐thin bezel surrounding the top edge of the notebook computer display. The antenna consisted of two radiating arms of unequal lengths to generate the lower and the higher bands. By properly loading each radiating arm with a shorting chip inductor, the proposed antenna was capable of generating the 2.4‐GHz (2400–2484 MHz) and the 5‐GHz (5150–5825 MHz) WLAN bands with a very low antenna profile. Good radiation characteristics were also obtained. The proposed design provides a feasible solution to the internal small antennas demanded by the current trend of the thin‐bezel notebook computers.
