The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a fractal circular monopole patch antenna. The other important property that is, Space-filling property which actually determines the reduction in the size of the antenna. This property adds more electrical length in less volume which reduces the size of ...

Abstract—This research is presented with microwave (MW) ablation by using the T-Prong monopole antennas. In the study, threedimensional (3D) finite-element methods (FEM) were utilized to analyse: the tissue heat flux, temperature distributions (heating pattern) and volume destruction during MW ablation in liver cancer tissue. The configurations of T-Prong monopole antennas were considered: Thre...

A folded loop antenna for handsets has already been introduced and shown as one of balanced feed antennas for handsets, which is very effective to mitigate the antenna performance degradation due to the body effect. In addition, to be lower profile of folded loop antenna, Built-in folded dipole antenna, which has a structure folded loop elements sideway so that the antenna can be placed on the ...

A novel compact UWB antenna with 3.5/5.5 GHz dual notch-band characteristics is presented. The proposed antenna has a simple structure and compact size of 30 × 35mm2. Firstly, a compact modified rotated monopole antenna that covers UWB band is achieved. Then by inserting a λ/4 stub and etching two symmetrical λ/4 L-shape slots on the UWB antenna achieved before, a dual band-notched ultra-wideba...

In this paper, a compact UWB printed monopole antenna design is proposed. The monopole antenna has the form of an E-shaped structure printed on a substrate with relative dielectric constant of 3.38, and thickness of 1.52mm. The matching through the UWB response is satisfied using a reduced ground plane. The proposed antenna is fed by a 50 Ω unsymmetrical microstrip line. The ground plane is pri...

An optimized design for the spanner shape regular hexagonal monopole (RHM) patch antennas has been reported to yield ultra wide band (UWB) impedance bandwidth. Impedance and radiation characteristics are presented and discussed. From the results, it has been observed that, the impedance bandwidth, defined by 10 dB return loss, can reach a value of 8.63GHz. A rectangular slit in the radiating pa...

We propose in this paper the design, realization and experimental characterization of a low-profile metamaterial “bent” monopole antenna with a total height of 0.027λ0 and a fractional bandwidth of 24.4% around 1.3GHz. The metamaterial (MTM) structure is a dual-layer mushroom-like electromagnetic band gap (DLEBG) conceived and optimized to improve the antenna’s operating bandwidth. Moreover, a ...

A multiband monopole antenna with modified fractal loop parasitic is presented. By adding bow-tie patches and a modified fractal loop to the sides and bottom of a strip line monopole, respectively, the presented antenna can generate the multi-resonant frequencies for the application of wireless communication systems. The characteristics of the presented antenna have been examined by using the s...
