The behaviour of various families of the antenna structures is studied. In that, CPW (Coplanar Waveguide) fed antennas show better behaviour for the Wireless applications. The slot antenna is used for precise operating frequency, where the frequency spectrum is 2.45GHz and 5.5GHz. To achieve the proposed frequency, the slot antenna is fed with Coplanar waveguide is implemented and measured with dimensions...
In this paper, a compact, high efficient CPW (co-planar waveguide) fed antenna which is used for various applications is proposed. In this work, the proposed antenna is evaluated using IE3D simulation software. The proposed antenna has the compact size of 16.55mm × 20.05mm × 1.6 mm and the substrate is RT_Duroid 5880 used (εr is 2.2 and tanδ is 0.0009). The antenna resonates at 8.5 to 8.7 GHz frequency,...
In this paper we discuss and create a MQTT based Secured home automation system, by using mentioned sensors and using Raspberry pi B+ model as the network gateway, here we have implemented MQTT Protocol for transferring & receiving sensor data and finally getting access to those sensor data, also we have implemented ACL (access control list) to provide encryption method for the data and finally...
In this paper, the CPW fed Z monopole antennas has proposed for Industrial, Scientific, and Medical (ISM) band (2.4–2.48 GHz) applications. To make the designed antenna suitable for implantation, it is printed on biocompatible Al2O3 ceramic substrate. The antenna was simulated by immersing it in a phantom liquid, imitating the electrical properties of the human muscle tissue. Simulations in various...
