This paper presents a simple antenna system for land vehicle communication aimed at Engineering Test Satellite-VIII (ETS-VIII) applications. The developed antenna system which designed for mounting in a vehicle is compact, light weight and offers simple satellite-tracking operation. This system uses a microstrip patch array antenna, which includes onboard-power divider and switching circuit for...

Detecting partial discharge (PD) is an effective way to evaluate the condition of high-voltage electrical equipment insulation. The UHF detection method has attracted attention due to its high sensitivity, strong interference resistance, and ability to locate PDs. In this paper, a miniaturized equiangular spiral antenna (ESA) for UHF detection that uses a printed circuit board is proposed. I-sh...

The principle of resistive charge division for position measurement was laid out by Radeka in 1974 [1] but, to date, has not been explored for estimating the longitudinal coordinate for silicon microstrip detectors. To exploit resistive charge division, the impedance of the readout structure must be large relative to the dynamic impedance of the amplifier circuitry. Somewhat counter-intuitively...

Conventional PCB processing of organic dielectrics has been proven to be a very economical interconnect solution for a variety of PCB, module, and packaging applications in the telecommunications and computing markets. Organic microvia dielectrics are well suited for mobile wireless as well as telecom and computing infrastructure products where the latest fabrication techniques, such as high-sp...
