Cr. Rowell et Rd. Murch, A COMPACT PIFA SUITABLE FOR DUAL-FREQUENCY 900 1800-MHZ OPERATION/, IEEE transactions on antennas and propagation, 46(4), 1998, pp. 596-598
Planar inverted F antennas (PIFA) have been proposed as possible candi
dates fur mobile telephone handsets, In this letter, we describe the d
esign of a compact PIFA suitable for operation at 900 MHz. In addition
, we provide modifications to this design that allow it to operate in
dual-frequency bands at 900 and 1800 MHz, Finite-differenee time-domai
n (FDTD) and experimental results are provided.
