Abstract
This paper introduces a novel technique for retuning the microstrip patch antenna (MSPA) during fabrication to meet the desired frequency. Designing the patch antenna is a rigorous process due to its very low manufacturing tolerances. To defeat such limitations of the microstrip patch antenna, a new technique named as dielectric constant engineering (DCE) is proposed. In this proposed method, a new formula is given to cut the dielectric material from the substrate part of the patch antenna during fabrication so that the targeted resonant frequency can be achieved without affecting patch dimensions. The process is suitable for multilayer substrates. This method is very useful for bulk fabrication of patch antennas. The results are simulated and verified using FDTD-based optimizing tool HFSS® version 11.
