Design of miniature microstrip antenna for ultra-wideband applications

In this paper, a novel rectangular shaped patch antenna is designed for Ultra-Wide Band applications. The studied antenna is compact and has a small size (20 mm x 21.5 mm) with a 50-Ω feed line and a partial ground plane which offer a very simple geometry. The antenna is printed on FR4 material which has a depth of 1.60 mm and a relative permittivity equal to 4.3.The different results are obtained using the CST Microwave Studio software. The antenna operates over a 3.12 GHz to 17.37 GHz range with a return loss less than -10 dB and voltage standing wave ratio (VSWR) less than 2.The reported antenna achieves a maximum gain of 5 dB.
