Passive feed methods for meshed antennas

Previous studies have concentrated on rectangular meshed patches. However, circular and triangular shapes can improve polarization and bandwidth characteristics not addressed in rectangular patches. One of the challenges with these shapes is effective feed design and an efficient fabrication method. To solve these two problems, we have examined several types of antenna feeds using inkjet printing with conductive ink on plastic substrate or copper tape on glass. Furthermore, it was found that printing methods are effective in fabricating meshed antennas and that passive feed methods can be easily and efficiently implemented for single patch or antenna array designs.
