Design a Hat Shaped Folded Patch Antenna For - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. The document describes a proposed design for a hat-shaped folded patch antenna for advanced wireless communication. Key points include:
- The antenna design involves a slotted hat-shaped circular patch, a double-sided printed circuit board, a metallic block, and dielectric substrate.
- Performance parameters like VSWR, axial ratio, gain, radiation pattern, impedance bandwidth, and circular polarization are evaluated.
- The antenna is miniaturized through folding the patch edge and adding slots, and beamwidth is enhanced by modifying the dielectric substrate thickness and metallic block height.
- The proposed antenna achieves wide azimuth coverage, high gain, over 10% bandwidth, and is suitable for applications in portable devices.
