Abstract
In this article, added microstrip line at the bottom area of printed circuit board (PCB) is proposed for improving the bandwidth of GSM900, DCS1800, and PCS1900. By printing the microstrip line at the bottom area of PCB, frequency bandwidth of slim-type cellular phone which has a low-profile monopole antenna is improved. Dimension of the microstrip line is 45 mm × 9 mm. The width and length of the microstrip line is modified for good bandwidth. The measured return loss of the antenna is better than 7.3 dB for low and high band. Measured peak gains of the proposed antenna present 3.41, 5.48, and 5.95 dBi in each band, respectively. Details of the antenna design are described. Its performances are also presented.
