This paper presents the design, testing, and analysis of a clover structured monopole antenna for super wideband applications. The proposed antenna has a wide impedance bandwidth (−10 dB bandwidth) from 1.9 GHz to frequency over 30 GHz. The clover shaped antenna with a compact size of 50 mm × 45 mm is designed and fabricated on an FR4 substrate with a thickness of 1.6 mm. Parametric study has been performed by varying the parameters of the clover to obtain an optimum wide band characteristics. Furthermore, the prototype introduces a method of achieving super wide bandwidth by deploying fusion of elliptical patch geometries (clover shaped) with a semi elliptical ground plane, loaded with a V-cut at the ground. The proposed antenna has a 14 dB bandwidth from 5.9 to 13.1 GHz, which is suitable for ultra wideband (UWB) outdoor propagation. The prototype is experimentally validated for frequencies within and greater than UWB. Transfer function, impulse response, and group delay has been plotted in order to address the time domain characteristics of the proposed antenna with fidelity factor values. The possible applications cover wireless local area network, C-band, Ku-band, K-band operations, Worldwide Interoperability for Microwave Access, and Wireless USB.

AbstractA low profile super-wideband polarization diversity printed monopole antenna with dual band-notched characteristics is presented the first time. The designed antenna comprises two arched shaped radiating elements with two triangular tapered microstrip feed lines (TTMFL) and two arched shaped partial ground planes, which covers an enormously wide impedance bandwidth (BW) from 1.2 to 25 GHz (ratio BW of 20.8:3) for reflection coefficient |S11| < −10 dB. To ensure the high port isolation (better than − 30 dB) between two feeding ports over the whole bands, two analogous antennas have been kept perpendicular to each other at a distance of 1 mm. In addition, the dual band-notched performance in wireless local area network (5–6 GHz) and X-band (7.2–8.5 GHz) is generated by employing a pair of open-circuited stubs (L-shaped stub and horizontal stub) to the TTMFL. Envelop correlation coefficient has been computed to study the polarization diversity performance. Finally, the proposed antenna was fabricated and tested successfully. Measured results indicate that the proposed antenna is an appropriate candidate for the polarization diversity applications. The proposed antenna has a compact size of 40 × 70 × 0.787 mm3, high isolation, and occupies a small space compared with the existing antennas.

Inherently UWB (Ultra Wideband) communication systems comes with interference problem with some if the existing narrowband communication systems. These bands are stopped with the help of band-stop filter in order to reduce electromagnetic interference However, the complexity and limitations are increased due to these filters, hence this solution is turned down in those applications where design complications and complexity is of concern. Introducing various slots of specific shapes and exact dimensions however, have solved this issue for the researchers around the world. This paper presents a hexagonal PMA (Printed Monopole Antenna) with triple stop bands. The antenna is used for UWB application. The antenna is stopped the WiMAX (Worldwide Interoperability for Microwave Access), WLAN (Wireless Local Area Network) and ITU (International Telecommunication Union) bands. The antenna dimensions are 30x28x16 mm3. FR4 is used between ground and radiating patch with relative permittivity of 4.4. The VSWR (Voltage Standing Wave Ratio) is less than 2 between 3-11 GHz except WiMAX (3.1-3.7 GHz), WLAN (5.1-5.8 GHz) and the ITU frequency band (7.95-8.4 GHz). The antenna is design in CST software.

A Co planner Wave Guide (CPWG) fed with octagonal patch antenna is modified from their respective rectangular patch are presented for WLAN application. The dielectric material applied in the design process for both co planar and micro strip patch antenna is FR4 Epoxy Glass, which has relative permittivity of 4.4 and substrate height 1.6mm. Antenna parameters used to check the performance. A comparison is made between the octagonal co-planar antenna and octagonal micro strip antenna available. Ansys HFSS is used for antenna design and analysis. Both designed antennas are suitable for wireless local area network application and the design parameters of the antenna are optimized to resonate at 3GHz frequencies for WLAN applications. It has been found that octagonal micro strip patch antennas have lower return loss and are more directive than co planar patch antenna. High directivity of octagonal micro strip antenna is due to the presence of ground plane under the substrate of antenna. The results obtained by simulations have also shown that octagonal co planar patch antennas have high radiation efficiency (a measure of the power radiated through the antenna as an electromagnetic wave to the power fed to the antenna terminals) and which implies a wider bandwidth as compared to an octagonal micro strip patch antennas. The radiation efficiency obtained for micro strip patch antenna is 24% and that for co planar patch antenna is 67%, the directivity for micro strip patch antenna is 3.75 dB and that for a co-planar patch antenna is 3.25 dB.

AbstractIn this paper, a novel bird face microstrip printed monopole ultra-wideband (UWB) antenna is investigated. The proposed compact antenna consists of a ring-shaped with additional slot and slotted ground plane on FR4 material. The overall electrical dimension of the proposed antenna is 0.25 λ×0.36 λ×0.016 λ and is energized by microstrip feed line.

The impedance bandwidth of the monopole antenna cover 3.1–12.3 GHz (9.2 GHz, BW) frequency range. The messurement displayed that the designed antenna achieved excellent gain and stable omnidirectional radiation patterns within the UWB. The maximum gain of 6.8 dBi and omnidirectional radiation pattern makes the proposed antenna that is suitable for UWB systems.

This paper presents a compact broadband printed monopole antenna with U-shaped slit in the partial ground plane and rectangular parasitic patches adjacent to the microstrip line for multiple applications. The optimal dimensions of the proposed antenna are 35 × 25 × 1.5 mm3 and is fabricated on commercially available low-cost FR4 substrate with εr = 4.3 and 0.025 loss tangent. Due to introduction of rectangular parasitic patches and U-shaped slit large bandwidth has been achieved. The impedance bandwidth (return loss, magnitude of S11 < 10 dB) of the proposed antenna is 139% (2.9–16.3 GHz). The proposed antenna covers ultra wide band applications, 5.2/5.8 GHz WLAN bands, 3.5/5.5 GHz WiMAX bands, X band (8–12 GHz), satellite communication, and other wireless communication services. The study shows that there is good agreement in simulated and measured results. Nearly stable radiation patterns have been obtained throughout the operating band. Antenna results and details are discussed and elaborated.

By introducing a modified F-shaped feeding strip and dual parasitic shorted strips, a small-size wireless wide area network/long-term evolution (WWAN/LTE) printed antenna is proposed and embedded in the 4 G mobile phone with octa-band operation. The operating impedance bandwidths (RL ≥ 6 dB) of 263/1093 MHz can be obtained across the LTE/WWAN bands, respectively. The overall antenna size of the proposed printed monopole antenna (MA) is only 35 × 10 × 0.8 mm3. Meanwhile, this small-size MA provides the measured peak gains and antenna efficiencies of 2.0/3.6 dBi and 80/75% for the LTE/WWAN bands, respectively.
