Abstract

A compact dual-band antenna for ISM (2.45GHz) or WiMAX (3.15GHz) applications by low-temperature co-fired ceramic (LTCC) technology is presented in this paper. The proposed antenna is composed of multi-layer structures to reduce the sizes effectively. The simulated results show that the dimensions of the antenna are 11×4.2×1.2mm3, with the 2:1 VSWR impedance bandwidth definition, the lower and upper band have the bandwidth of 80 and 90 MHz. The novel antenna has realized miniaturization and omni-directional radiation patterns across the whole operating frequency band.
