This paper presents one compact printed monopole antenna with one chip inductor embedded on the radiation elements. By introducing the chip inductor, the resonant frequency of the original antenna can be decreased by more than 37% while there is no significant influence on its radiation characteristics including radiation efficiency and antenna gain. Meanwhile, after adding the chip inductor, the...
In this paper, a new multiband antenna consisting of a coplanar patch antenna over an active artificial magnetic conductor (AMC) ground plane is demonstrated. The AMC ground plane, which has been proven to be very effective in the design of low profile antennas, consists of 4×4 square shaped unit cells. By connecting RF switches between adjacent unit cells, a group of four unit cells can be aggregated...
This article presents the design and fabrication of a simple printed fractal monopole antenna for WLAN USB dongle applications. The proposed antenna uses the combination of meander line and fractal geometry, which is very simple and easy to fabricate, to achieve a multiband operation characteristic. The parameters of this antenna were optimized through numerical simulations in Ansoft HFSS, after which...
This work studies dual-band EBG structures used as an artificial magnetic conductor (AMC) ground plane for WLAN co-planar antenna to achieve a low profile structure. From the simulation results, the EBG surface geometry with Jerusalem Cross (JCSS) slot has been chosen in this study. A dual band prototype operating at 2.4 and 5.2 GHz has been implemented and tested. The results show that the EBG antenna...
