A compact Luna shaped high gain UWB antenna in 3.1 GHz to 10.6 GHz using FR4 material substrate

The microstrip antenna mainly consists of four modules. They are ground plane, dielectric substrate, feed line and radiating patch. Most of time, the patch, feed line and ground plane use copper material whereas the substrate will take different dielectric materials. Hence, the antenna substrate mat...

Description
Summary:The microstrip antenna mainly consists of four modules. They are ground plane, dielectric substrate, feed line and radiating patch. Most of time, the patch, feed line and ground plane use copper material whereas the substrate will take different dielectric materials. Hence, the antenna substrate material plays a major role on antenna performance characteristics. This paper presents different types of antenna substrate materials available and also describes the effect of FR4 substrate material on a compact Luna shaped high gain UWB antenna in the frequencies starting from 3.1 GHz to 10.6 GHz. So, this design is produced on the FR4 substrate of size 20 × 18 × 1.6 mm3. It results in S11 ≤ -10 dB from 3.09 GHz to 11.02 GHz. It observes highest radiation efficiency as 98% at 8.6 GHz and maximum peak gain as 5.68dBi at 9.7 GHz. The study of fractional grounds with different types of slots is also shown. The simulation software used is ANSYS HFSS. The simulated and measured return loss is compared.
