Compact band notch ultra wide band microstrip antenna for short distance wireless applications

In this paper a simple design, compact size, and low cost ultra wide band (UWB) rectangular patch antenna with defective ground plane with WLAN (5.5GHz) band notched characteristics is proposed. The band notch is created by inverted V slot on rectangular patch. The proposed antenna is designed on FR4 substrate of size 18 × 24 × 0.8mm. The antenna achieves an operational bandwidth from 3.3 GHz to more than 10.6GHz up to 12.3 GHz which can be used to increase the wireless data transfer rate for short distance wireless devices.
