ABSTRACT: By 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.
