Abstract :
Miniaturized printed-circuit-board antennas are proposed in PCMCIA cards for WLAN and Bluetooth applications. The proposed antenna is a straight F in shape printed on a FR4 substrate together with the rest of the circuit components, providing a low-cost antenna solution. The straight F antenna resembles a printed inverted F antenna, but the inductive tuning arm is in the same side of the capacitive arm, resulting in further reduced overall antenna area. The proposed antenna occupies an area of about 9 mm by 7 mm. Several prototype antennas are designed and fabricated. Reasonable impedance bandwidth and good range of coverage are found.
