A novel compact cable-fed antenna for a GSM/DCS handset

Abstract

By using a branch‐line ground plane, a monopole radiator, and parasitic patches, a newly compact cable‐fed antenna is investigated in order to overcome the thickness problem of the planar in‐ verted‐F antenna (PIFA). The designed antenna has dimensions of only 40 × 12 × 1 mm and the impedance bandwidth of the proposed antenna is able to cover the GSM, DCS, and PCS bands. © 2005 Wiley Periodicals, Inc.

A novel reconfigurable multiband slot antenna fed by a coplanar waveguide using radio frequency microelectro‐mechanical system switches

“…The rapid increase of communication standards leads to a great demand in developing multiband internal antennas for handset devices [1, 2]. Nowadays, mobile devices need to simultaneously handle multiple services that include a wide range of standards such as GSM900 (Global System for Mobile Communication, 880–960 MHz), GPS1575 (global positioning system, 1570–1580 MHz), DCS1800 (Digital Communication System,1710–1880 MHz), PCS1900 (Personal Communication System,1850–1990 MHz), UMTS2100 (universal mobile telecommunication system, 1920–2170 MHz), WLAN2400/5250/5800 (wireless local‐area network, 2400–2484 MHz/5150–5250 MHz/5725–5825 MHz).…”
