Abstract

An integrated wireless impulse generator has been designed, simulated, fabricated and tested. Switched oscillator topology has been used as an impulse generator. A switched oscillator consists of a low impedance transmission line, which is charged by a DC source with a large input impedance. The transmission line is connected to a fast closing switch at one end and a high feed-point impedance antenna at the other end. After charging the transmission line, closing the fast switch short circuits the transmission line, resulting in a transient wave propagating toward the antenna. The mismatch between transmission line characteristic impedance and the antenna feed point impedance causes a reflection at the antenna terminal. Due to the short circuit at switch terminal, the reflected signal will reflect back at the switch terminal as well. This back and forth reflection generates a series of pulses at the antenna terminal which will be radiated by the antenna. The switched oscillator impulse generator is designed to operate in the industrial, scientific and medical (ISM) radio frequency band.
