In this paper, A miniaturized monopole UWB antenna with λ/4 meander slot line is presented. To achieve a considerable miniaturized antenna, a reference bowtie monopole antenna was simplified using the perfect magnetic wall condition. Also, to obtain rejection characteristic at the interference bandwidth of 5 GHz-WLAN, a meander shaped slot line was inserted at ground patch. In comparison with reference...
In this paper, a dongle-type RFID PIFA (Planar Inverted F-Antenna) structure with a resonance frequency of 920 MHz is optimized taking into account the robustness against noise factors. To achieve this, a global optimum is first sought out by means of the evolution strategy and then the robust design of the optimized antenna structure is obtained by introducing the Taguchi loss function. The validity...
