Abstract
In this paper, we propose a internal antenna for wirless HDMI dongle device using the folded monopole structure. The proposed antenna is for 2.4GHz and 5.8GHz. The antenna optimized for parameters length, gap, width, and radius of semicircular of monopole antenna using the 'F' structure. To confirm the characteristics of the antenna parameters, HFSS from ANSYS Inc. was used for the analysis. We used an FR4 dielectric substrate with a dielectric constant of 4.4. The HDMI dongle size of the proposed antenna is 45×20×1mm, and the size of the antenna area is 5×20mm. There is a value of return loss less then -10dB in 2.4GHz and 5.8GHz, band and the maximum antenna gain is -4.13dBi. The result proved the possibility of the practical using 'F' structure that came frin comparing and analyzing the measured and simulated data of the antenna.
