“…To emphasize the distinctiveness of the proposed antenna, Table 2 compares the features of the proposed antenna with other published works. Each design in [9][10][11][12][13][14][21][22][23][24] was compared with our proposed design in terms of physical size, electrical size, ka factor, operating frequency, BW, realized gain, and efficiency. The data presented in Table 2 demonstrate that the proposed design has the smallest size with the exception of the design presented in [9].…”

This article presents a highly miniaturized dual-band electrically small antenna (ESA) for on-demand 3.6 and 5.8 GHz wireless applications. A partial rectangle-shaped structure is printed on the back face of the dielectric material, forming the antenna's ground (GND) plane. The radiating structure of the antenna consists of a C-shaped structure and a U-shaped ring connected to it, which is printed on the dielectric material's front face. The overall dimensions of the designed antenna are 0.160λo × 0.160λo × 0.02λo at the lowest operating frequency. The proposed antenna has a ka value of 0.56 at the lowest operating frequency, which is 3.59 GHz. Thus, the proposed antenna is considered as electrically small. The characteristic mode analysis is adopted to provide a clear understanding of the antenna's resonance behavior. The antenna has been fabricated and the simulation results were validated through measurements. Good agreement between simulated and measured results was obtained. Dual-band operation at 3.62 and 5.75 GHz was achieved, according to the measured reflection coefficient. The proposed antenna offers an adequate performance in terms of gain and efficiency, based on simulation and measurement results. Because of these characteristics, the antenna is well-suited to new wireless applications.

“…Dual-band antenna [4] is realized using two patch radiators suspended over ground plane, but resulting structure has relatively thick substrate about 0.09λ. Miniaturized dual-band antennas are achieved by incorporating multiple ground slots [8,9] and result in 64% and 46% size reduction, respectively. However, the reason for multiple slots on patch is not explained in both papers.…”

“…Although such antennas exhibit high gain, they may be not suitable to accommodate inside modern wireless devices. Loading schemes such as inclusion of stubs, shorting pins, and slot cut techniques also yield multi-band operation [5][6][7][8][9][10]. Main advantage of short and slot loading technique is the miniaturization unlike the stub loading technique.…”

New designs of dual and triple band rectangular microstrip antennas employing modified ground plane profiles are proposed. Slots introduced in the ground plane not only tune the higher order mode resonance frequency of the radiating patch but also alter the current distributions on the ground which yields multi-band response showing reduced cross polar level radiation pattern. Dual and triple band antennas yield 1 to 2% of impedance bandwidth at each frequency with gain around 1.5 to 2 dBi. Also in the multi-band design, 35% reduction in patch size against the conventional half wavelength counterpart is obtained. Further resonant length formulation at modified patch modes is presented which gives closer prediction of calculated frequency than the simulated value. The proposed multi-band design can find applications in personal communications systems requiring frequency agile capabilities.

This paper deals with the study of multiband printed antenna coated with silver nanomaterial to obtain better performace in the antenna characteristics. The techniques adopted in the study are etcing of novel patch with definitive dimensions as the fucntion of chosen operating wavelength at 8 GHz as the design constraint along with defective ground layer to minimize the propogation losses in the antenna. From the results, it is clear that, the antenna obtained 61.20% improvement in bandwidth for the fabricated Multiband Printed Antenna with Defected Ground Structure (MPA DGS) and 32.10% bandwidth improvement for Nanomaterial Coated Multiband Printed Antenna with Defected Ground Structure (NCMPA-DGS)(NCMPA-DGS) with quad-band characteristics suitable for Wireless applications. The proposed antennas are compact in nature which has also achieved good radiation characteristics.
