In this paper a novel differentially fed Ultra-Wide Band (UWB) antenna in low-temperature co-fired ceramics (LTCC) technology to be used in the 60 GHz band for integrated RF front-ends is presented. The antenna is based on the aperture stacked patch fed via H-shaped aperture to achieve more than 10 GHz operational bandwidth. The antenna is fed by a parallel-wire transmission line which enables ...

The explosive advancement of wireless communication devices for multiband and multi-standard applications such as Wi-Fi, WiMAX, Bluetooth, and cellular networks demands low-cost, lightweight, small form factor, and high performance radio frequency (RF) front-end modules. In the multiband or multi-standard devices, the bandpass filter (BPF) is an essential functional block to avoid signal interf...

The L-type Ca(2+) channel (LTCC) is the major mediator of Ca(2+) influx in cardiomyocytes, leading to both mechanical contraction and activation of signaling cascades. Among these Ca(2+)-activated cascades is calcineurin, a protein phosphatase that promotes hypertrophic growth of the heart. Coimmunoprecipitations from heart extracts and pulldowns using heterologously expressed proteins provided...

In this article, a system-on-package (SoP) approach for Bluetooth system module applications using low-temperature co-fired ceramic (LTCC) technology is presented. The developed LTCC integrated substrate for our Bluetooth module application is overall 12 12 1 mm in size, with integration of two originally proposed components, a balanced-to-unbalanced bandpass filter and a folded meander-line in...

Loss of cardiac myocytes in heart failure is thought to occur largely through an apoptotic process. Here we show that heart failure can also be precipitated through myocyte necrosis associated with Ca2+ overload. Inducible transgenic mice with enhanced sarcolemmal L-type Ca2+ channel (LTCC) activity showed progressive myocyte necrosis that led to pump dysfunction and premature death, effects th...

A surface layer of a ceramic substrate can be modified by introducing a second phase into a melt pool generated locally by a laser beam. CuO, WO3 powders with nanosized particles were used to alloy alumina and a glass ceramic LTCC (Low Temperature Co-fired Ceramic). Depending on the process parameters the nano-particles were melted during the laser process and solidified during cooling in the c...

A novel explicit knowledge embedded space mapping (SM) optimization technique is presented in this paper. It generalizes the implementation procedure of the efficient SM technique by introducing a buffer space called embedded knowledge space between the original coarse model space and the fine model space, where the ingredients of the coarse model space can be completely different from those of...
