Abstract
A dual-band antenna designed at the wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) bands is presented compact split circular ring shape dual-band antenna with open ring and addition strip. Its size is compact by the recondition circular ring shaped resonator connected. The antenna is fabricated onto a printed circuit board (PCB) on FR-4 substrate and the relative permittivity of 4.4, an overall size of 23 mm × 30 mm × 0.8 mm. This antenna can easily adjusted with open ring and strip to match impedance using a 50 ohm transmission line with SMA connector. The measured results show that the compacted antenna achieves a dual-band operating bandwidth from 2.38 GHz to 2.56 GHz and 4.66 GHz to 7.29 GHz for 11 S below -10 dB and the antenna yields omnidirectional patterns. The measured gains of the antenna from 2.45 and 5.5 GHz frequencies are 1.55 dBi and 3.2 dBi, respectively.
