Abstract
A low-profile, conjoined and yet decoupled two-monopole design for Wi-Fi 6E notebook applications is presented. The single monopole antenna has a small size of 4 mm × 18.7 mm. The antenna is composed of a two-branched monopole with two shorting inductors for producing the 5 GHz (5150–5825 MHz) and 6 GHz (5925–7125 MHz) bands, and an inductor loaded at one branch end and connecting to a tuning portion for 2.4 GHz (2400–2484 MHz) operation. Two symmetrical monopoles are further conjoined by a chip inductor that connects the open ends of the tuning portions, forming a compact footprint of 4 mm × 38.4 mm for the two-notebook antenna design. With the use of the decoupling inductor and a proper two-monopole arrangement, acceptable isolation and a low envelop correlation coefficient (ECC) can be attained.
