✦ Synopsis

This paper presents design simulation, implementation, and measurement of a miniature GPS/K-PCS dual-band LTCC chip antenna for mobile-communication handsets. The dimensions of the LTCC chip antenna are 9 ϫ 15 ϫ 1.2 mm. The lower meander-type antenna is tuned to the lower-frequency (GPS) band and the upper meander antenna with via-hole connection contributes to the higher-frequency (K-PCS) band. In order to lower the resonant frequency for the GPS band, a printed modified meander antenna with gap stub is used for integration with K-PCS band operation. The measured impedance bandwidths (VSWR Յ 2) are 55 and 120 MHz at the resonant frequency, respectively.

## Abstract A novel dual‐band monopole antenna, created by loading a meandered wire to an inverted‐L wire monopole, is proposed. The antenna is suitable for applications in GSM/DCS dual‐band mobile phones. Both the inverted‐L wire and the meandered wire operate as quarter‐wavelength structures, and
