information between two or more points that are not physically connected. Distances between the two points can be short or as far as thousands or even millions of kilometers. Different ways can be used to establish wireless communication. Basically‚ antennas are used as transmitter and receiver in wireless communications like cellular telephones‚ satellite communications‚ radio broadcasting‚ etc. Despite many advantages of wireless communication there are many factors that affect the quality of wireless

number of pre-orders Apple had received in a single day for any device up to that time. By the end of the month‚ Apple had sold over 1.7 million iPhone 4s’. Not long after the release‚ customers began to report antenna issues with the phone. They said that if they touched the antenna located on the outside of the phone or gripped the phone too hard‚ they would lose reception and their phone calls would drop. With such high demand for the iPhone 4‚ one would think that Apple would have ensured their

ENGINEERING DISASTERS We can also call Engineering as in invisible science. No one can actually see how it works but it actually exists like an air. Example: Plain flies‚ building stands and many more. We don’t think how a building can stand weight without collapsing. Similar to apple’s company’s Moto ‘it just works. Here the main problems are not the designs but the material the use up building that design. The concept of total cost minimization is the roots of such accidents that just ruins lives

PROCESS ANALYSIS INTRODUCTION There are clearly more questions than answers right now about what has caused Apple’s iPhone 4 woes -in particular‚ the phone’s antenna design and the company’s struggle with supply and demand. Apple recently released the fourth generation iPhone with a design flaw in the antenna that substantially degrades the reception when held in the palm of your hand. This‚ in turn‚ has created the problems the company has had with meeting the needs of the consumer‚ as well

Volleyball Court Dimensions Measurements‚ Centerline‚ Antenna Understanding volleyball court dimensions has big impact on how well you play the game of volleyball. The volleyball court specifications require the court to be 18 meters (60 feet)long and 9 meters (30 feet) wide. The volleyball court has acenterline that divides each teams side into a 9 by 9 meter area of court space. The volleyball net is one meter wide and is placed in the center of the court running sideline to sideline. For

efficiency can approach close to 100%. We can more concentrate the transmitted microwave power to the receiver aperture areas with taper method of the transmitting antenna power distribution. Famous power tapers of the transmitting antenna are Gaussian taper‚ Taylor distribution‚ and Chebychev distribution. These taper of the transmitting antenna is commonly used for suppression of sidelobes. It corresponds to increase the power transmission efficiency. Concerning the power transmission efficiency of the

CHAPTER I THE PROBLEM AND ITS SETTING INTRODUCTION The area of wireless power transmission is very interesting. The technology is in its infancy but the overall benefits from its maturation could be significant to society as a whole. World population is expected to continue to grow exponentially. Five sixths of the world’s population lives in developing nations. Most developing nations such as China‚ India‚ and Pakistan are rapidly improving their standard of living. All of these trends point
