摘要：

In this paper, a capacitive coupling Low Temperature Co- fired Ceramics (LTCC) chip antenna is designed and fabricated for Wideband Code Division Multiple Access (W-CDMA) mobile handsets applications. The proposed antenna is designed by utilizing the capacitive coupling structure and feeding by a microstrip line. The proposed antenna has the advantage of good gain and easy to impedance matching. The size of the proposed antenna is 3 x 10 x 0.94mm(3). Gain difference by microstrip- fed and CPW-fed is also discussed and comparative results are simulated and demonstrated. Measured results show that the impedance bandwidth for |S11| less than - 10 dB covers two bands of W-CDMA, and the omni-directional radiation pattern is realized.
