Description: There is a demand for compact, low profile antennas for modern wireless devices. The purpose of this dissertation is to develop tools that antenna designers can use to create such antennas. The Left-Handed Material zero degree cell can be modified to allow for vias in the structure to radiate. This dissertation focuses on those vias and provides techniques to allow them to radiate in three different ways. The first technique allows the designer to match the input to the source. The second technique is a method of cascading LHM cells that also allows the antenna designer to match the input impedance. Lastly, LHM cells can be combined in a way that can exhibit a dual resonance. This dual resonance can be used to create a dual band antenna or a single band antenna with enhanced bandwidth.
