## Abstract By placing a rectangular spiral conducting strip on the top, bottom, and two side surfaces of a rectangular plastic chip of dimensions 5 × 10 × 16 mm^3^, a novel plastic chip antenna capable of GSM/DCS dual‐band operations in mobile phones is presented. The plastic chip antenna has the
## Abstract A novel open‐loop antenna with a coupled‐line gap for application as an internal laptop antenna for GSM/DCS dual‐band operation is presented. Owing to the use of the coupled‐line gap, the proposed antenna can operate both as a half‐wavelength loop structure at 900 MHz and a one‐waveleng
## Abstract A dual‐band dual‐polarized antenna suitable for operation in telecommunication base stations is presented. One of the bands covers the GSM band, while the other covers both the DCS and UMTS bands. The design is compact and yields good radiation characteristics, with excellent isolation
## Abstract A novel dual‐band single‐layer patch antenna that covers the bands of 890–960 MHz for GSM and 1710–1880 MHz for DCS, with VSWR ⩽ 2:1, is presented. This antenna consists of a ground plane, air spacing (without dielectric substrate), and a metal patch layer printed on a thin substrate wi
