Enhancing Antenna Gain Using 2D- EBG Structures for C-Band Applications

This paper presents a novel Electromagnetic Band Gap (EBG) structure designed to enhance antenna performance. The proposed antenna features a rectangular patch fed by a 50 a SMA coaxial probe. The structure includes an innovative EBG rectangular box with four supports of Neltec NX9240 material, and its design and parametric analysis were conducted using Ansys HFSS simulation software. Utilizing a Rogers RT/duroid 5880 substrate with a relative permittivity of 2.2, this design significantly improves gain and reduces return losses. The proposed antenna achieves a gain of 12.60 dB and demonstrates substantial performance enhancements at the C-Band, particularly beneficial for radar and satellite communication applications.
