Item Design and Simulation of a Wearable Micro strip Patch Antenna for Healthcare Monitoring Applications(Department of Electronic and Telecommunication Engineering, IIUC, 19-10) Mamun, Sultan Shah; Majumder, Md.Qudrat-E-AlahiItem DESIGN AND SIMULATION OF MICRO STRIP PATCH ANTENNAS FOR 5G WIRELESS COMMUNICATION(Department of Electronic and Telecommunication Engineering, IIUC, 19-10) Soliman, Md Mohiuddin; Hakim, Mohammad LutfulItem Study and Analysis of the Radiation Effects of the Cellphone, BTS Tower and Local Wi-Fi Router on Human Body(Department of Electronic and Telecommunication Engineering, IIUC, 19-10) Islam, Syed Mainul; Bhattacharjee, Shashwata; Azim, Md. AnwarulWe are regularly in contact with electromagnetic radiation in our daily life. From the radiation produced by mobile phone to that derived from X-ray check-ups, electromagnetic waves appear to be present in current standard of living. In the electromagnetic spectrum, higher frequency has taken great attention for wireless communication with better efficiency. But as much as we like the availability of higher data rate, it comes at a price of increased vulnerability of health hazards. A summary of all non-ionizing health effects has been compiled and an analytical discussion on it due to long term exposure to radiofrequency radiation. In this work an analysis of less hazardous manipulative safe distance between individuals and wireless devices such as- BTS antennas and WIFI routers based on calculating Specific Absorption Rate (SAR) on human body at different distances from BTS and WIFI routers is proposed. Finally, different safety distance for individuals for different WIFI router and different BTS antenna types are proposed in this research.Item A Network infrastructure for Smart Home(Department of Electronic and Telecommunication Engineering, IIUC, 19-09) Mohiuddin, Talha Misbah; Riyad, Md. Kamrul HassanAbstract There are uncertainties with regard to which network technologies will remain current and adaptable to emerging changes in Smart Home requirements. This research is based on using the existing and available network technologies for Smart Homes. In particular, it used CSMA network and Wifi Network based on IEEE 802.11ac standard. It is expected that a usual home has to upgrade the infrastructural network to fully upgrade into Smart home. So, the focus is to make a building design, based on Bangladesh’s prospective and use CSMA and WiFi network individually in simulation.Item A High Gain And Wideband 2x2 Array Antenna Design of Microstrip Patch Antenna(MPA) for 5G Application(International Islamic University Chittagong, 19-10-12) Dini, Abshir Mohamud; Mohamed, Yusuf MohamedAbstract Due to their low cost, low profile and ease of manufacturing in the circuit boards, microstrip antennas have become a part and parcel of today's wireless communication world. But poor performance, such as low capacity handling, narrow bandwidth, low gain, etc. In some cases, limit their application. Since high frequency bands will be used in the upcoming wireless communication of the 5th generation (5 G), it will be severely affected by path loss. High gain antenna is required to manage this problem. So the main concern of this research work is to design a high gain 2×2 microstrip patch antenna array. The simulation is performed by using the simulation software Computer Simulation Technology (CST) Microwave Studio which is a commercially available electromagnetic simulator based on finite difference time domain technique. The gain, bandwidth, return loss, VSWR and efficiency of the designed 2×2 array antenna is 23.8 dBi, 600MHz, 74.3dB, 1 and almost 99% respectively.
