A small size broadband microstrip patch antenna for 14.0GHz radar application with multiple substrates had been fabricated using LTCC technology. A combination of a relatively low dielectric constant LTCC substrate and a relatively high dielectric constant LTCC substrate had been incorporated to reduce the effect of trade-off relationship between antenna(More)
A broadband circularly-polarized (CP) stacked patch antenna to be realized in LTCC (low temperature co-fired ceramic) technology was presented. The proposed antenna was composed of the two-layer stacked patch and LTCC substrate. It was shown that the wide bandwidth was caused by a two-frequency resonance. The CP operation was obtained by cutting corners.(More)
