Especially, the antenna is fed by using a technique of capacitive coupling to achieve the impedance bandwidth for supporting the operating frequency band of wireless
communication systems, including 2.45 GHz, 3.50 GHz, and 5.20 GHz, respectively.
The antenna covers the operating frequency
band applications of the wireless communication standard,
including IEEE 802.11 a/big (WLAN), IEEE 802.15.1a
(Bluetooth), IEEE 802.16a (WiMAX), and IMT advanced system
(4G mobile communication system), respectively. Moreover, the
radiation pattern is improved to propagate the omnidirectional
pattern at all of operating frequency bands, due to the fractal
ring. The experimental
