Abstract

With the recent development of micromachining technology, there is an increased interest in incorporating rectangular microstrip patch antennas with other components fabricated with this technology. However, micromachined circuits are usually fabricated on high dielectric constant substrates and are required to operate in high frequencies; these conditions lead to degradation of the antenna radiation pattern and polarization characteristics and undesired coupling between array elements. Several approaches have been proposed in order to reduce surface wave power excitation. Jackson et al. (1993) achieved a complete elimination of the dominant TMo surface wave mode for circular patches, by use of a specific design of the antenna element. In this paper, a similar approach is followed for the rectangular patch, in an effort to reduce significantly the TMo surface wave mode.
