The device was developed by Ramirez and Roger Green in the university of Warwick?s engineering department. It brings benefits to wireless networks, electronic households and data transfer. It applies techniques used to manipulate radio frequency to select the incoming ?signal frequency ? carried on the infrared beam to produce the optical equivalent of the radio. Optical antenna serves the same purpose as in electronic one .It must collect energy from an area and channel it t o the receiving element. Optical antenna uses a combination of precis ....etc

An antenna is defined by Oxford Dictionary as ? a usually metallic device for radiating or receiving radio waves ?. The IEEE Standard Definitions of terms for Antennas ( IEEE Std 145-1973) defines the antenna or aerial as ? a means for radiating or receiving radio waves ?. In other words the antenna is the transitional structure between free-space and a guiding device. The guiding device or transmission line may take the form of a coaxial line or a hollow pipe (wave guide) and it is used to transport electromagnetic energy from the transmitting ....etc

Design and development of X-band micro strip patch antenna

Introduction


In high-performance aircraft, spacecraft, satellite and missile applications, where size, weight, cost, performance, ease of installation, and aerodynamic profiles are constraints, low profile antennas may be required. These antennas should have low profile, conformable to planar and non-planar surfaces, simple and inexpensive to manufacture using modern printed-circuit technology, mechanically robust when mounted on rigid surfaces, compatible with MMIC designs, and ....etc

In paper based financial messaging system, the messages are sent in defined formats duly signed by the authorized signatories. Paperless initiative and changes in the business practices have changed the authorization process. In electronic messaging, the messages are created, authenticated electronically and sent through electronic medium. Present technology facilitates data transmission with security integrity duly taking care of confidentiality and nonrepudiation of messages. Encryption and digital signature play a vital role in providing suc ....etc
