Abstract
This paper discusses numerical design and experimental characterization of dualband printed monopole antenna with center frequency of 1.6GHz and 2.4GHz. The antenna that takes a shape of G letter is proposed to overcome the special need of GPS and WLAN application. The antenna which is fed by microstrip line extended from a center pin of 50Ω connector type has 2 distinct arms in different length arrangements to obtain the desired different resonant frequencies. After obtained the appropriate numerical design, the antenna is then deployed on an FR4-Epoxy dielectric substrate with the dimension of 50mm × 50mm and the thickness of 1.6mm. From the measurement results, it shows that the characteristics of realized antenna have good agreements each other with the numerical design. The realized antenna is able to operate at dual frequency bands where the working bandwidths for lower and higher frequency band are up to 220MHz and 150MHz, respectively.
