Design and Analysis of Microstrip Patch Antenna Using Periodic EBG Structure for C-Band Applications

摘要

In this paper, an Electromagnetic Band Gap structured microstrip patch antenna is presented. The proposed antenna consists of a rectangular patch which is fed by way of 50 ohm microstrip line feed. This antenna occupies a totally very small area of 22x22x0.8 mm(3) etched on FR4 substrate, making it suitable for C-Band applications. The substrate has relative permittivity of 4.4. The unit cells are etched on the dielectric substrate with 10 mmx10 mm size. This antenna improves the gain and decreases the return losses. This proposed antenna has the improve gain of 8.5112 dB. The merits are miniaturized size and at comfortable structure.
