Abstract
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.
