Ground plane Embedded antennas use ground planes on the host pcb in order to radiate efficiently. The ground plane constitutes half of the antenna, so respecting the recommendations provided in the ...

The varactor control circuitry uses the output from an on-chip phase-locked loop (PLL) synthesiser and from the power amplifier to work out the correct capacitance to tune for deviations in the loop ...

The corner of the PCB is generally the best place to position an antenna. That’s because a corner position allows the antenna to have clearance in five spatial directions, and the feed to the ...

This paper presents the test results of an electrically small loop antenna sensor towards detecting the radiated magnetic field due to partial discharge (PD) activities. The loop antenna prototype was ...

My new DSP/SDR-Rx ATS-Mini arrived with a telescopic antenna and a “Donut WB Antenna (10 kHz – 180 MHz)”. While the receiver works well with the whip antenna, the loop antenna failed to perform. The ...

The partial discharge phenomenon in high voltage equipment has a very significant impact on the lifetime of the equipment. Increasing of the application of the integrated power modules on the ...
