  1. Capacitive RF MEMS Switch Design and Simulation

    by , 14th October 2017 at 13:25 (Anil Pandey : Electronics Design and Simulations)
    The switching is required in many applications at low as well as at high frequency. RF MEMS switches are the specific micromechanical switches that are designed to operate at RF to mmWave frequencies. MEMS switches usages some mechanical movement to achieve a closed or open circuit in the Radio Frequency transmission lines. GaAs FET switches do not have sufficient isolations to minimize cross interference and signal jamming from channels is close proximity. MEMS switches provide high isolation ...
  2. RFID Tag and Reader Antennas

    RFID stands for Radio-Frequency Identification. The RFID device provides a unique identifier for that object and just as a bar code or magnetic strip the RFID device must be scanned to retrieve the identifying information.

    RFID System Working Principal

    A RFID system has three parts:

    A scanning antenna
    A transceiver with a decoder to interpret the data
    A transponder – the RFID tag – that has been programmed with information

    ...

    The helix antenna is a travelling wave antenna, which means the current travels along the antenna and the phase varies continuously. Helix antennas (also commonly called helical antennas) invented by John Kraus give a circular polarized wave. Helix antennas are referred to as axial-mode helical antennas. The benefits of this helix antenna are it has a wide bandwidth, is easily constructed, has real input impedance, and can produce circularly polarized fields. ...

    In many applications pertaining to missile, satellite, spacecraft and aircraft a directive antenna mounted on a curved body is required. Conforming the antenna to the surface save space and is often essential for structural reasons. An antenna that conforms to a surface whose shape is determined by considerations other than electromagnetic; for example, aerodynamic or hydrodynamic called conformal Antenna. Microstrip antenna technology is most suitable ...

    Time Domain Reflectometry is the analysis of conductor lines (interconnects)by sending a pulsed signal into the conductor and then examining the reflection of that pulse. A TDR transmits a short rise time pulse along the conductor. If the conductor is of a uniform impedance and is properly terminated, the entire transmitted pulse will be absorbed in the far-end termination and no signal will be reflected toward the TDR. Any impedance discontinuities will cause ...
