Abstract
AbstractBy loading a chip inductor of suitable inductance (about 12 nH or less) to a planar inverted‐F antenna (PIFA) with a shorted rectangular spiral strip, the frequency ratio of the antenna's first two resonant frequencies can be controlled, which makes dual‐frequency operation with a desired frequency ratio easy to achieve. In addition, with the use of a shorted rectangular spiral strip, the proposed PIFA, has compact dimensions for a fixed dual‐frequency operation. Design examples of the proposed PIFA with a compact size of 7.2 × 10 × 26 mm3 to achieve dual‐frequency operation at about 900 and 1800 MHz are presented. © 2002 Wiley Periodicals, Inc.
