Develop a small and dual-band operated antenna module using stacked LTCC technology. The proposed antenna will be operated GPS and PCS frequency band
In this study, we propose a novel small chip antenna module which is operated in GPS and K-PCS frequency bands. Three types of antennas having meander type radiating elements are fabricated using stacked LTCC sheets(Dupont : DP 9599), and experimented the electrical characteristics.
The study objects are focused in two areas, 1) novel structures of radiating elements for small antenna Two types of novel antenna structures are proposed using cavity model analysis for a single meander line antenna. A meander line antenna with expanding stubs in radiating elements show larger frequency changes than a meander line antenna with gap stubs. A small sized GPS antenna is proposed using inserted gap stubs meander line stacked structured LTCC substrates.
2) GPS and K-PCS frequency band small antenna using single feed A mutual coupling effect change the operating frequency and FR(Frequency Ratio) of the meander line stacked structured LTCC antenna, the optimization of the via-hole height was studied.
An novel type of an optimized small dual band-chip antenna module ( 9×15×1.2mm), was proposed using stacked LTCC(dielectric constant =7.8) sheets. It shows omni-directional radiation patterns. The fabricated antenna can be used in PCS terminal , and the stacked LTCC antenna technology will be used in a broad range of applications for the future communication handset systems.
In this studying duration, 8 papers were published and 2 patents are pending.
