  • Abstract This thesis proposes a design of microstrip monopole antenna with dual-band operation. The proposed antenna is composed of a straight-line section and a balanced fold-line section. In recent years, the demand for portable radio communication has been increasing which required low profile, light weight and small size antennas. Therefore, the size of the antenna is required to be as small as possible.
       Microstrip antennas have the advantage of light weight, small size and low cost and have been used in commercial products extensively. They have played the important role in wireless communicating applications recently.Microstrip antennas can radiate in broadside and act in resonant mode but restricted by its impedance bandwidth. Therefore, how to increase the bandwidth of microstrip antenna has been the major researching topic. In this thesis, we have investigated and analyzed the characteristics of the impedance bandwidth and radiation pattern of a compact size dual-band antenna with a small ground plane. All the properties of the dual-band antenna include the bandwidth, radiating pattern, and gain variation can satisfy the Bluetooth and IEEE 802.11a/b/g specifications for WLAN applications. Experimental results show good agreement to simulation predictions obtained from commercially available IE3D software.
