This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...

Fractal antenna, as name concerns, uses fractal i.e. structure does not change and repeat it when large focus has created upon it. This repetition feature of this antenna provides a great flexibility that it can be designed and can used in different frequencies. These antennas gives a finite area of coverage but the diameter of perimeter becomes infinite. Fractal antenna is used in most of the ...

A novel planar circular Apollonian fractal shaped UWB monopole antenna with band rejection capability is presented in this paper. The antenna performs satisfactorily in the frequency range 1.8–10.6GHz which gives a wide impedance bandwidth of 142% for VSWR within 2. The proposed antenna has the capability to reject the frequency band 5.125–5.825GHz assigned for IEEE802.11a and HIPERLAN/2. This ...

In this paper, the synthesis of a three-band planar antenna working in the GSM (900 and 1800 MHz) and UMTS frequency bands is presented. As reference geometry, a hybrid prefractal shape has been adopted by integrating a Sierpinski-like and a Meander-like structure. The synthesis of the antenna has been performed by optimizing the descriptive geometrical parameters of the reference shape by mean...

This paper presents a design of E-shaped rectangular fractal antenna and the excitation is provided by using the microstrip line feeding technique. FR4 glass epoxy is used as a substrate material with relative permittivity 4.4, thickness 1.6mm and the resonant frequency is taken as 3.2GHz for the designing of proposed antenna. The three iterations is designed and simulated by using HFSS V13 (Hi...

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...
