Abstract

Design of Double Notch Band Half-Elliptical Shape Reconfigurable Antenna for UWB Applications

Highlights

  • The UWB technique during the last 20 years has been used for many applications, for example, sensing and military applications, radar, etc

  • The Federal Communications Commission (FCC) for commercial use allocated the frequency band from 3.1 GHz to 10.6 GHz

  • To reach such a condition, there are a large number of an excellent antenna designs about this topic, one of these antennas was the half-elliptical microstrip antenna, which is used to operate on the overall UWB frequencies [2]

Summary

Antenna Structures

The UWB reconfigurable antenna patch can extend the operating frequency band by expanding the width of the radiating patch. The UWB characteristic has been achieved by optimizing the parameters (i.e., R1, R2 and R3) of the patch and the height (Lg) of the ground plane. At the notch band frequencies, the currents pass nearby the embedded slots are the most considerable factor, even with oppositely flowing directions around the slot boundaries. The preferred attenuation close to the notch band frequencies can be created.
