An Internal Dual Band Antenna for Bluetooth / DMB Applications
Soon Ho Hwang, Young Jun Cho, Seong‐Ook Park · 2005
An internal dual band antenna is proposed for Bluetooth and digital multimedia broadcasting (DMB) services. This novel antenna, fed by a 50 /spl Omega/ coaxial cable, operates at the Bluetooth (2400-2483 MHz) and DMB (2535-2655 MHz) bands, respectively. The size of this antenna is 17/spl times/10 mm/sup 2/ and its height is 7 mm. When this antenna is applied for handset case, the bandwidth of presented antenna is 290 MHz starting from 2400 MHz to 2690 MHz for VSWR <2.0. The simulated and measured results were obtained by considering the antenna with and without the handset case, including battery.
