Abstract-The performance of a compact circular polarization (CP) textile antenna is presented. The design is based on the traditional CP rectangular truncated patch antenna. Four slits are introduced at every edge of the rectangular truncated patch antenna to make it compactness. Simulated results show that the proposed antenna can have an antenna reduction of about 18% compared to the traditional one. A good bandwidth (2.40 GHz -2.50 GHz) with axial ratio (AR) bandwidth (2.41 GHz -2.44 GHz) and gain of 5.70 dB is presented. This antenna is suitable for application of wireless monitoring communication system and Wireless Local Area Network (WLAN) application.

Abstract-This paper discusses about an ongoing project that serves the needs of people with physical disabilities at home. It uses the Bluetooth technology to establish communication between user's Smartphone and controller board. The prototype support manual controlling and microcontroller controlling to lock and unlock home door. By connecting the circuit with a relay board and connection to the Arduino controller board it can be controlled by a Bluetooth available to provide remote access from tablet or smartphone. This paper addresses the development and the functionality of the Android-based application (Android app) to assist disabled people gain control of their living area.

Abstract-Ultra wideband radio (UWB) is a promising technology that offers exceptional data rates for short range communication. This paper presents the analysis of the IEEE 802.15.4a UWB physical layer (PHY), a novel short range wireless communication technology, for wireless sensor network (WSN) applications. We analysed and compared the performance of the UWB PHY using the MIXIM framework for a discrete event based simulator called OMNeT++. In this context, we present the simulation and implementation of line of sight (LOS) and non line of sight (NLOS) channel models with a variety of configurations such as data rates, bandwidth and forward error correction. An analysis on bit error rate (BER) over distance will be discussed in order to evaluate the channels performance. The results will serve as a base for future studies on deploying IEEE 802.15.4a based sensor networks with specific characteristics.
