ABSTRACT: In this paper, a circuit model is developed in RF ADS in
order to simulate the coupling effect of a retracted whip on a planar
inverted-F antenna (PIFA) for wireless-handset application. The PIFA is
designed as the main antenna of the handset to cover the 800-MHz
(824–894 MHz) and 1900-MHz (1850–1990 MHz) bands. A parasitic
whip antenna is used to improve the performance of the PIFA, especially
when the handset is used against the human head. In such a
whip–PIFA combination environment, the retracted whip will degrade
the PIFA performance if it is not designed carefully. The purpose of this
paper is to present an efficient method to optimize the PIFA performance
when the whip antenna is in the retracted position.
Key words: dual-band; PIFA; whip; wireless handset
