N2 - In this paper, a novel and compact dual-band planar monopole antenna with well-tuning mechanisms of each individual band is proposed. This antenna is fabricated on a low-cost, easily available FR4 substrate by using etching or milling machines. The lower operation frequency can be adjusted to cover GSM 1800 band (1805 - 1880 MHz), and the upper band covers Worldwide Interoperability for Microwave Access (WiMax) band (3.3 GHz) for more than 200 MHz. After setting the desired operation frequencies, a thin wire and microstrip pad is designed to achieve dual-band matching. The overall antenna area is compact and effectively shrinks to 0.018λ02. Compared with other miniature antennas, our proposed antenna still maintains high efficiency. The measured antenna gains are from -1.78 to -1.12 dBi and from 1.05 to 2 dBi at its low and high frequency band, respectively.
