Circuital Design and validation of Switching circuit for Time-Modulated Antenna Array

The circuital design of electronic switch to provide supply to an antenna for time-modulation is presented in this work. The designed circuitry is validated by measuring voltage, current, and power levels during ON and off state employing AWR. Working of the circuit in AWR is tested for various RF power input levels during ON and OFF instants. The designed high speed switch is employed on two-element Time-Modulated Antenna Array (TMAA) forms sum-difference patterns in fundamental and first harmonic frequencies respectively. The radiation power beams measured by employing proposed switching circuitry are validated with the beams measured from MATLAB.
