  • Abstract In this thesis, we present the investigation of a Planar Inverted-F antenna design for IEEE 802.11a/b/g (WLAN), 802.16 (WiMAX), and Bluetooth wireless applications. The frequency ranges of interest are 2400~ 2500 MHz, 3300~ 3700 MHz, and 5100~ 5900 MHz. The proposed triple-band Planar Inverted-F antenna is obtained by adding a parasitic element to a dual-band antenna. Also, the bandwidth of the entire antenna is increased accordingly. To achieve low profile and compact design, meander slot and defected ground are used.
    HFSS software is applied to simulate the proposed design. After simulation, the proposed design is fabricated on the FR4 print circuit board (PCB). The antenna is mounted on 80x 30x 0.8mm3 PCB substrate and fed by a 50 ohm microstrip due to the consideration of the practical handheld device size. The dimension of the proposed antenna is 15.5×10.5×4 mm3. The experimental results including the measurements of reflection coefficient and radiation patterns have a good consistency with the simulated results.
