Novel Miniaturized Multiband and Wideband PIFA Antenna for Wireless Applications

Design of multiband antennas with low volume is of practical interest for the ever growing wireless communication industry. In this paper, the design of PIFA antenna with multiband resonance for WiMAX, WLAN, HIPERLAN/2 applications by using genetic algorithm (GA) is presented. Genetic algorithm (GA) method was used to design the shape of the patch and the shape of the ground plane simultaneousl...

A Compact Coupled-Line Multiband Microstrip Antenna

A multiband microstrip antenna is proposed in this paper. By using a circular slot at the ground plane, the circular radiation at the antenna frequency resonances has been achieved. A patch is designed with a coupled U-shaped line. To gain resonance at the lower frequency, a microstrip line is introduced at the middle of the circular slot. The assessment of the proposed antenna shows good agree...

CPW-Fed UWB Compact Antenna for Multiband Applications

A planar UWB antenna with added GSM 1800/WMTS and UMTS bands is presented. A CPW-fed circular patch is used to obtain wideband characteristic covering the UWB range. A novel slot formed by merging the alternate sides of a hexagon with isosceles triangles is inserted in the patch to obtain dual-band operation with the lower band suitable for GSM 1800 operation. By inserting a bent monopole in th...

Design of Compact Multiband EBG and Effect on Antenna Performance

This paper presents the design of Electromagnetic Bandgap (EBG) structure using fractals geometry and its effect on antenna performance. The EBG structure has been designed on substrate єr = 4.3 and thickness h = 1.53 mm. The 1 iterative EBG structure offers the surface wave attenuation around 20 dB down from 2.94 GHz to 4.58 GHz corresponds to 43.62% bandwidth. The experimental results of 2 it...
