Printed PIFA EM Compatible With Nearby Conducting Elements

A novel printed planar inverted-F antenna (PIFA) with two shielding strips to allow the antenna to be electromagnetic (EM) compatible with nearby conducting elements is presented. That is, the proposed printed PIFA can be placed in very proximity to nearby conducting elements with small or negligible effects on the antenna performances. This attractive feature is mainly because the antenna's possible EM fringing fields are suppressed by the two added shielding strips at the feed and end portions of the printed PIFA. Details of the proposed printed PIFA are described, and a design example for wireless local area network operation in the 2.4 GHz band is studied.
