Miniaturized, Wi-Fi 6E Notebook Antenna Using an In-Series Chip Inductor

A very compact and small, printed notebook antenna using an in-series chip inductor for achieving miniaturization for 2.4/5 and 6 GHz Wi-Fi 6E operation is introduced. The antenna consists of a coupling strip and a parasitic strip embedded with a chip inductor. The coupling strip can produce a wideband, covering the 5 GHz (5150–5825 MHz) and the new 6 GHz (5925–7125 MHz) bands. The inductor largely decreases the required resonant path for the 2.4 GHz (2400–2484 MHz) band. The design occupies a footprint of 5 mm × 10 mm (0.04-λ ×0.08-λ at 2.4 GHz), which may be the smallest notebook antennas in the recent published works. In addition, compared with the previous study in [1], the size reduction reaches more than 30% in this work with the in-series inductor.
