Broadband tapered slot antennas monolithically integrated on ion damaged silicon-on-sapphire substrates are driven by picosecond photoconductivity to generate and detect millimeter waves. The time-dependent electromagnetic impulse response of these transceivers is modeled by relating the antenna structure and the shape of the exciting pulse. The far-field response is observed to consist of a traveling-wave component and a standing-wave component, which is also predicted by the model.

    When microstrip antennas (MSAs) are optimised, the full-wave electromagnetic simulation takes long time to get the result which is very time consuming. Hence, the knowledge-based neural network (KBNN) is used here to replace the electromagnetic simulation to shorten the calculating time and...
