Bandwidth Improvement of Stub Loaded Compact Ultra-Wideband Microstrip Patch Antenna for C/X-Band Applications

In this research paper, a square ultra-wideband microstrip antenna is designed on a compact ground of size 24 × 24 mm 2 using low cost FR-4 substrate. Antenna patch is designed by successively loading four rectangular patch segments of different sizes (antenna-1 to 4) and a square shape stub on top...

Zusammenfassung:	In this research paper, a square ultra-wideband microstrip antenna is designed on a compact ground of size 24 × 24 mm 2 using low cost FR-4 substrate. Antenna patch is designed by successively loading four rectangular patch segments of different sizes (antenna-1 to 4) and a square shape stub on top of radiating patch (antenna-5). The radiating patch is optimized by parametric analysis of square shape stub. The impedance bandwidth (S 11
