Miniaturized dual-band wireless local area network antenna using low-temperature co-fired ceramic technology

摘要

A very compact wireless local area network antenna using meander striplines in three low-temperature co-fired ceramic layers is designed and fabricated in this study. This chip antenna has a small volume of only 3.2 1.6 2 mm 3. The measured radiation bandwidths (voltage standing wave ratio 2) of 2.45 and 5.8 GHz are 110 and 150 MHz, and the peak gains of the two bands are 1.6 and 2.7 dBi, respectively. The resonant frequencies can easily be tuned by adjusting the inner coupling between different patterns and the length of the striplines. Besides, no via-hole was used in this structure, which guarantees the easy fabrication and high production.
