    Public believed that radiation leakage from microwave ovens was similar to atomic radiation that could lead to serious health problems, including cancer. For many years up to now, domestic microwave ovens were not considered to leak levels of microwave radiation that caused concerns; consequently, they have not been regularly monitored. According to Australian Standard 3301, the maximum allowable ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (326 KB) | HTML iconHTML

    Calculable antenna is used as a reference antenna for antenna calibration to obtain accurate antenna factor. This paper focuses on calculable biconical antenna with low uncertainty. The proposed biconical antenna factor can be derived either by simulation or by analytical method. The antenna factor is directly derived from antenna gain. Therefore, the uncertainty could be improved due to no measur... View full abstract»

    In microwave power amplifier (PA) design, high linearity is required in order to maintain the integrity of the amplified, modulated signals. High spectral efficiency in a communication signal can be achieved by the use of non-constant envelope modulations, which place particularly high demands on the PA linearity. High power efficiency is also increasingly important, given the drive to control CO<... View full abstract»

  • Tuning circuit based on varactor for tunable filter

    Publication Year: 2011, Page(s):26 - 28
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (848 KB) | HTML iconHTML

    A tuning concept of a quarter wavelength side-coupled ring resonator is proposed by introducing varactor diode as tuning device at the four corners of the ring resonator to allow modification of the ring electrical length. This modification is typically used to allow the variation of the capacitance as a function of bias voltage thereby resulting in center frequency tuning. A complete tunable circ...

    Multiple stop-bands are required in order to suppress interference in radio spectrum with multiple wireless systems operating in it. In addition, wireless communication systems usually require small devices to fulfill the miniaturization requirements and simplicity of mobile unit. As a result, this paper is to propose a novel miniaturized matched band-stop filter with high rejection level. This fi... View full abstract»

    The wideband transceivers like the software defined radio require designing wideband RF hardware covering octave bands. The local oscillator of the mixer should be a wideband frequency synthesizer. Building on the theory of oscillations in the voltage controlled oscillator, the paper reviews the concept of negative resistance in the transistor circuit with some base inductance. It also provides si... View full abstract»

    A novel fourth order coupled lines filter topology is presented based on two parallel paths containing quarter-wavelength coupled lines. Three identical coupled lines are combined in series in each path to form a ring structure. This configuration leads to the compactness of a highly selective filter. The proposed filter is designed for wideband applications whose center is at 3 GHz with a fractio... View full abstract»

    Ground penetrating radar (GPR) is widely used in subsurface utility mapping for extracting the position (x, y) and depth (z) information of the utility. This information is crucial for subsurface facility management, in particular as reference in excavation works. The locational and depth information of the utility features is therefore of very important in subsurface mapping, apart from the relia... View full abstract»
