Abstract :
This paper presents the theory, analysis, and design of differentially-driven microstrip antennas. The theory is based on the extended improved cavity model. The analysis is focused on the input impedance and radiation characteristics. It is found that that the occurrence of resonance for a differentially-driven microstrip antenna also depends on the ratio of the separation xi of the dual feeds to the free-space wavelength lambda0. When the dual feeds are located far from each other xi/lambda0>0.1 in an electrically thin substrate, the resonance occurs. The design procedure is developed and verified with HFSS simulations
