A method for tuning an antenna includes cutting a portion of a metal pattern molded with a plastic insert to adjust electrical characteristics of the antenna. Tuning can be performed by cutting the metal pattern or by cutting the completed antenna including both the metal pattern and the plastic insert.

Method of mechanically tuning antennas for low-cost volume production

A multiband antenna includes a 5-6 GHz PIFA surrounded on two or three sides by a 2.4 GHz RFPIFA. The PIFA and RFPIFA are tunable by removing fingers from the PIFA and either removing portions of or creating at least one area in the RFPIFA where inductance may be added. The RFPIFA contains an inductive meanderline. An out-of-plane matching stub is provided between the feed and the ground plane to impedance match the antenna. The PIFA/RFPIFA is supported by a plastic mesa tabletop whose legs are mounted directly to the ground plane of a PCB at the corner of the PCB. Electronic components on the PCB can be mounted underneath the multiband antenna.
