Abstract :
This paper proposed a novel chip type ceramic dielectric antenna by using the advanced meander line technique for 2.4/5.8 dual ISM-band applications. This antenna is composed of a ceramic dielectric (8×4×1.5 mm3, alumina) and substrate (1.52 mm thickness, TMM-4). And to minimize the antenna´s available area on the substrate and to reduce the coupling effect with the ground plane, the antenna is located on the corner of substrate. The measured bandwidth and maximum radiation gain of the proposed antenna is 2.35-2.57 GHz(VSWR<2), 2.07 dBi @2.44 GHz and 5.29-6.01 GHz, 1.17 dBi @5.75 GHz. From the result, it is demonstrated that our proposed antenna can be applicable to the dual-ISM band applications.
