Abstract :
In this paper, we proposed an asymmetry structure of printed dipole antenna which acquires wideband impedance match delivered by a double-side and center-feed-design and an open slot in the small radiator to expand the high resonant frequency band and harvest an antenna that can reach dual and wide band requirements as we proposed here. The frequency bands of this proposed antenna cover 2.31-3.83 GHz and 4.88-6.0 GHz, which can be applied to WLAN and WiMax operations and the fractional bandwidths reach 49.51% and 20.59%. We minimize the antenna size to 20×47 mm2 by using the feed lines as design parameters to achieve the dual-band and wideband design. This proposed antenna structure can be included in a WLAN/WiMax array antenna as a structural element. In this paper, we will present simulation and implemented results of antenna structure, frequency bands, gain value and the radiation patterns.
