Abstract :
It is found that, to achieve stable oscillation and a well defined broadside radiation pattern from a self-oscillating microstrip antenna, the feed point should be located close to one end of the microstrip. Additional impedance matching is necessary to ensure that the correct mode of oscillation is excited.
