Abstract:

In the past few years, miniaturized antenna design has attracted the attention of researchers because of the huge demand for compact portable microwave devices. In this article square stub, meandered lines, a reverse L-shaped resonator and a ring resonator have been arranged to form the CRLH-TL (Composite Right/Left Transmission Line) which results in a miniaturized dual-band antenna configuration. The designed antenna configuration has an overall electrical outline area of 0.31\lambda_{0}\times 0.09\lambda_{0}, where \lambda_{0} is the wavelength in free space around the ZOR (zeroth order resonance) frequency of 2.72GHz. The dual-band characteristics of the designed antenna arrangement offer 7.35% and 11.07% −10dB fractional bandwidth around the resonance frequencies of 2.72GHz and 5.51GHz respectively. Additionally, in the direction of broadside radiation this antenna configuration provides an average gain of 1.51dB and 1.94dB throughout the −10dB working bands. The proposed dual-band miniaturized antenna have average radiation efficiency of 91.78% and 95.45% throughout the −10dB operational bandwidths. The developed antenna structure can be utilized in distinct microwave communication applications, such as WLAN (5.15-5.35,5.47-5.725 GHz), and Wi-MAX (5.2-5.8 GHz).
