In this paper the behavior in the neighborhood of broadside for 1D periodic microstrip leaky-wave antennas is investigated. As is well known this type of antenna is characterized by a radiated beam that is frequency scannable from the backward to the forward quadrant; however the presence of an open stopband results in undesirable scan performance near broadside. Here the open stopband is thoroughly characterized and related to different types of discontinuities within the unit cell through a comparison with the results obtained for a strip grating; moreover, a technique is described in order to obtain a minimization of the stopband effects.

Abstract
In this paper the behavior in the neighborhood of broadside for 1D periodic microstrip leaky-wave antennas is investigated. As is well known this type of antenna is characterized by a radiated beam that is frequency scannable from the backward to the forward quadrant; however the presence of an open stopband results in undesirable scan performance near broadside. Here the open stopband is thoroughly characterized and related to different types of discontinuities within the unit cell through a comparison with the results obtained for a strip grating; moreover, a technique is described in order to obtain a minimization of the stopband effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
