Abstract
compact planar inverted F antenna (PIFA)
with a tunable frequency response is presented. Tuning of
the resonant frequency is realized by loading a varactor on
an embedded slot of the proposed antenna structure with-
out further optimizing other antenna geometry parameters.
The antenna exhibits a wide frequency range from 1570 to
2600 MHz with a good impedance matching (S11

-10dB)
covering the GPS, PCS, DCS, UMTS, WLAN and LTE
systems. To validate the theoretical model and design con-
cept, the antenna prototype was fabricated and measured.
The compact size of the antenna is 15 mm × 8 mm × 3 mm
,
which makes this antenna a good candidate for mobile
handset and wireless communication applications.
