A Novel Compact Wide Band CPW fed Antenna for WLAN and RFID Applications

TLDR: A wide band CPW fed antenna for wireless communication applications such as WLAN, RFID and RFID, which has desired antenna characteristics such as return loss better than 10dB, VSWR, gain and radiation pattern at the specified resonant frequencies is presented.

Abstract: A wide band CPW fed antenna for wireless communication applications such as WLAN (5.2 GHz) and RFID (5.8 GHz), is presented in this paper. The antenna consist of finite substrate dimensions (20×15 mm 2 ).This antenna is realized on FR4 epoxy substrate with permittivity 4.4 and loss tangent of 0.002.It has desired antenna characteristics such as return loss better than 10dB, VSWR, gain and radiation pattern at the specified resonant frequencies. The B.W of antenna (1130 MHz) is greatly improved by optimizing the width and length of the slots. The antenna is simulated using Mentor Graphics IE3D 15.10 electromagnetic solver and fabricated. There is good matching between measured and simulated results.
