Small chip antenna for 2.4/5.8-GHz dual ISM-band applications

We propose a novel chip-type ceramic dielectric antenna using the advanced meander line technique for 2.4/5.8-GHz dual ISM-band applications. The proposed antenna is composed of small ceramic dielectric (8 mm /spl times/ 4 mm /spl times/ 1.5 mm, alumina) and substrate (thickness of 1.52 mm, TMM-4)....

Zusammenfassung:	We propose a novel chip-type ceramic dielectric antenna using the advanced meander line technique for 2.4/5.8-GHz dual ISM-band applications. The proposed antenna is composed of small ceramic dielectric (8 mm /spl times/ 4 mm /spl times/ 1.5 mm, alumina) and substrate (thickness of 1.52 mm, TMM-4). In order to minimize the antenna's available area on the substrate and to reduce the coupling effect with the ground plane, the antenna is located at the corner of the substrate. The measured bandwidths and maximum radiation gains are 2.35-2.57 GHz, 2.07 dBi at 2.44 GHz (VSWR
