In this research article, a compact dual band asymmetric coplanar strip-fed printed antenna is designed and presented for Bluetooth, WLAN/WiMAX and public safety applications. The dual frequency operating bands (2.45 GHz and 5.25 GHz) have been achieved by attaching two simple meander shaped radiating strips to the ACS feed line. The proposed antenna geometry is printed on a low cost FR4 substrate...
In this research paper, a compact, novel O-shaped ACS fed dual-band monopole antenna for 2.4 GHz Bluetooth/WLAN, 4.9 GHz US public safety band and 5.0 GHz WLAN/WiMAX applications is presented and investigated. The proposed geometry consists of an O-shaped radiating branch, monopole-shaped radiating branch and a rectangular shaped uniplanar ground plane, which occupies an overall size of 20 × 12.5...
A miniaturized half-mode substrate integrated waveguide (HMSIW) antenna is presented which resonates at a frequency of 6.78 GHz. The S-parameters and radiation patterns are investigated by full-wave simulation and the simulated results show the unidirectional radiation pattern. The proposed is single layered, compact in size, and can be easily integrated with planar PCB technology. It also takes the...
In this paper, the dual-band slot antenna operating at 32 and 42 GHz for 5G mobile communication is presented. The presented design consists of an elliptical slot with sectored radiating patch to increase the antenna bandwidth and also to minimize the interference between 5G and other communication devices. The simulated result shows that the presented antenna has dual-band at 30.5–32 GHz and 40.5–42...
A tri-frequency CPW-fed monopole antenna is proposed. The antenna is printed on a substrate with a couple of unequal monopoles and asymmetrical ground plane. In addition, a inverted L-shaped stub is added on the ground plane to get third resonant frequency so that antenna offers three resonant frequencies at 1.42 GHz, 1.82 GHz and 2.62 GHz for the commercial wireless applications. The simulated results...
This paper introduces a new type of hexagonal shaped geometry based on metamaterial structure. The antenna structure developed the advantage of CPW feed to obtain wide bands and metamaterial structure to reduce size of the desired antenna. Dimensions of the proposed geometry of antenna is 29.6×21.7 in mm and thickness of dielectric substrate is 1.6 mm. The antenna is designed with RT Duroid material...
Wireless Mesh Networks (WMNs) consist of mesh clients and mesh routers, where laptops, cell phones and sensor nodes are mesh clients, while mesh routers with minimal mobility are used for data forwarding. In this paper we focus on the improvement of wireless mesh network performance using smart antenna, and in particular, switched beam directional antennas. We have used STDMA(Spatial Time Division...
The last few years have experienced a high growth rate in research area of wireless mesh networks (WMNs). The attractive characteristics of WMN are self-organize and self-configure, low set-up/installation costs, simpler maintenance tasks, and service coverage with high reliability and fault-tolerance. WMN also provides their integration with existing wireless networks such as cellular networks, WLANs,...
