Broadband Triple-Frequency Microstrip Patch Radiator Combining a Dual-Band Modified Sierpinski Fractal and a Monoband Antenna

“…Various techniques have been used to achieve this matching by using substrate material that has a dielectric constant with high value, patches that have slots in them, fractals, defected ground structure, electronic band gap structures, metamaterials, and shorting pins and plates [3][4][5][6][7]. Apart from losses there are methods to improve the efficiency, bandwidth, and gain, which can be achieved by increasing the height of the dielectric substrate, decreasing the relative permittivity, and performing dual-band operations [8,9]. A fractal antenna is commonly used for multiband applications.…”

Abstract:An ultrawideband antenna array using a right-angled isosceles triangular microstrip antenna as a basic element is presented using inset feed for applications in the Internet of things. A Koch fractal antenna array with defected ground plane is used to generate multiband applications. Further, meander lines are added to increase the equivalent inductance that reduces the size of the antenna and increases the bandwidth and gain. Antenna arrays have been constructed and experimentally studied. The measured results show good agreement with the numerical prediction and wideband operation.

“…Several designs related to dual-frequency antenna have been reported [1][2][3][4][5][6]. Fractal antennas have been successfully designed as a compact high-performance multiband planar antenna [7][8][9][10][11]. These antennas based on conventional transmission lines (TLs) with single branch of dispersion curve use multi separate resonant paths of different lengths of resonators operated at half or quarter wavelength modes to obtain the dual resonances.…”

Abstract-A compact waveguide (CPW)-fed dual-frequency planar monopole antenna is proposed, which can excite two modes. The antenna is composed of a epsilon negative (ENG) meta-structured transmission line (MTL) unit cell and a monopole. The first resonance is zeroth-order mode, which is described using dispersion relation of ENG MTL based on Bloch and Floquet and designed on a CPW single layer where vias are not required. And the second is electromagnetically coupled monopolar mode. The zeroth-order resonant phenomenon is employed to reduce the antenna size. To design and analyze the proposed antenna, the circuit simulation of the ENG MTL unit resonator is executed by the equivalent circuit, and the results are compared with those of full wave simulation and experiment. The results show that the presented antenna has a reasonable radiation characteristics of bandwidth gain and size, verified by a commercial EM simulation software HFSS11, and is suitable for compact dual-frequency antenna. Then the antenna is fabricated and measured. The realized antenna has a compact size of 0.288λ 0 × 0.199λ 0 × 0.011λ 0 (25.1 mm × 17.4 mm × 1 mm) at 2.43 GHz. Simulated and experimentally measured results show that the proposed antenna can operate at 2.41 (2.43) GHz and 4.11 (4.14) GHz bands, respectively. Good agreement between the simulated and measured results is obtained.
