“…The intrinsic characteristics of such material are the relative permittivity ( r ), the dielectric loss (tan δ) and the thickness of the substrate (t) should be correctly chosen because the size of an antenna depends on the ε r and the tan δ [20]. However, to guarantee high network performance and wide bandwidth, the tan δ should have a low value [21]. In order to achieve this objective, in this study we have chosen the FR4 Epoxy substrate and Marble dielectric resonator as material for designing the proposed antenna.…”

The current work presents a novel cylindrical dielectric resonator (CDR) antenna geometry operating at 28 GHz for fifth-generation wireless communication networks (5G). Because of its high radiating power factor, the used dielectric resonator is regarded as a promising new candidate in the field of antennas. The CDR antenna is made up of a FR4 Epoxy Resin substrate with a relative permittivity of 4.4 and a height of 1.8 mm, to which we added a dielectric resonator with a relative permittivity of 8.3, a height of 1.5 mm and a radius of 1.34 mm and it fed by a single microstrip line. The designed antenna geometry was simulated and optimized with the electromagnetic solver HFSS, and the results were validated with the CST microwave studio software. The results allowed us to obtain an antenna radiation at the desired frequency of 28 GHz with an interesting return loss value, a good radiation pattern, a high gain, a large bandwidth and a high directivity. As a result, this antenna is suitable for a wide range of wireless satellite applications.

“…Furthermore, the filter geometry is bulk and resistant to integration and miniaturization. To address the issue, alternative methods such as the use of photonic band gap (PBG) structures, 12 stubs for tuning, 13 defective ground structure (DGS), 14 and hybrid new structures 15 have been implemented. Liu, Haiwen, and Sun employ 2D PBG structures to suppress harmonic formation in a patch antenna, and suppressing third harmonics has been employed 16 .…”

A novel multi-band clover leaf-shaped fractal antenna with integrated filtering to reduce higher order harmonics has been proposed. Existing microstrip filtering antennas endure limited gain, narrow impedance bandwidth, and undesired frequency radiations. The proposed antenna is designated to operate simultaneously in following operating bands: 3.35-3.6 GHz for WiMAX, 5.156-5.825 GHz for WLAN, 5.7-6.4 GHz for Intelligent Transport Systems (ITS), and 7.7-8.5 GHz for ITU-R applications. The proposed patch is realized by combining two semi-fractal ring microstrip patches like the geometry of a three-leaf clover with dual-layered stepped impedance resonator (SIR) integrated at bottom layer of the second substrate. The SIR bandpass filter exhibits odd and even modes suppresses higher order harmonics and undesired radiations. An aperture coupled feeding in the proposed patch offers better bandwidth and impedance matching. The number of iterations is increased to get the desired multiband characteristics. The proposed microstrip fractal antenna has the geometrical dimensions of 50 Â 50 Â 2 mm 3 . It is observed that both the simulated and measured results offers peak gain of >5 dBi and better return loss (S 11 ), that is, 3.3-3.6-GHz band offers S 11 of À33.73 dB, 5.15-5.825-GHz band offers S 11 of À36.69 dB, and 5.795-6.4-GHz band shows the S 11 of À36.25 dB, and for 7.725-8.5 GHz, the return loss is À33.209 dB.Harmonics at 6.42 GHz (1.8f 0 ), 7.37 GHz (1.5f 0 ), and 9.04 GHz (1.73f 0 ) has been suppressed and shows linear polarization in the WLAN band and circular polarization in the ITU-R and WiMAX bands.

A novel multi-band clover leaf shaped fractal antenna with integrated filtering to reduce higher order harmonics has been proposed. Existing microstrip filtering antennas endure limited gain, narrow impedance bandwidth, and undesired frequency radiations. The proposed antenna is designated to operate simultaneously in following operating bands: 3.35–3.6 GHz for WiMAX, 5.156–5.825 GHz for WLAN, 5.7–6.4 GHz for Intelligent Transport Systems-ITS, and 7.7–8.5 GHz for ITU-R applications. The proposed patch is realized by combining two semi fractal ring microstrip patches like the geometry of a three-leaf clover with dual layered Stepped Impedance Resonator(SIR) integrated at bottom layer of the second substrate. The SIR band pass filter exhibits odd and even modes suppresses higher order harmonics and undesired radiations. An aperture coupled feeding in the proposed patch offers better bandwidth and impedance matching. The number of iterations is increased to get the desired multiband characteristics. The proposed microstrip fractal antenna has the geometrical dimensions of 50 × 50 × 2 mm3. It is observed that, both the simulated and measured results offers peak gain of > 5dBi and better return loss (S11) i.e., 3.3–3.6 GHz band offers S11 of -33.73dB, (5.15-5.825) GHz band offers S11 of -36.69dB, (5.795-6.4) GHz band shows the S11 of -36.25 dB and for (7.725-8.5) GHz, the return loss is -33.209 dB. Harmonics at 6.42GHz (1.8f0), 7.37GHz (1.5f0) and 9.04GHz(1.73f0) has been suppressed and shows linear polarization in the WLAN band and circular polarization in the ITU-R and WiMAX bands.
