  • Microstrip Patch Antenn Antenna Theory Of Analysis And Design

    1.1 Overview: In antenna theory of analysis and design, the most forward looking topic is microstrip patch antenna. Microstrip patch antennas are made to have many different geometrical shapes and dimensions but among all the shapes of microstrip patch, four of them are most common than another that are square, rectangular, dipole and circular. They are employed in wide range of modern applications because of their easiness to design and compatibility with printed-circuit technology. The basic form of microstrip patch antenna is consists a patch and a ground plane that are separated by dielectric substrate as shown in Figure 1.1. The surface of the bottom side of a thin dielectric substrate is fully covered with metallization that act as a…

  • Disadvantages Of RFID Technology

    RFID TECHNOLOGY Radio-frequency identification (RFID): RFID Technology is a wireless electromagnetic field that is used to transfer data, or to identify people or objective, for the purposes of automatically identifying and tracking tags attached to objects. RFID is very fast, reliable and does not require any physical sight or contact between reader and scanner and the tagged items. There are some tags contains electronically stored information. It refers to small electronic devices that…

  • Radio-Frequency Identification: RFID Tags

    Radio-frequency identification also known as RFID is the use of wireless technology that uses electromagnetic fields to transfer data, for the purpose of automatically identifying and tracking RFID tags that are attached to objects. The RFID tags will have information that is electronically stored. Some of the tags will be powered by an electromagnetic induction from magnetic fields that are produced near the readers. Certain RFID tags will collect energy from the reader’s radio waves and will…

  • Radio Frequency Identification (RF And RFID?

    NFC and RFID Radio Frequency Identification (RFID) is a wireless use of electromagnetic fields to transfer data, aiming to automatically identifying and tracking tags attached to objects. Near Field Communication (NFC) is one specific type of RFID, and shares many physical properties with it. The differences between NFC and RFID is that many extra properties were developed for NFC to enable secure mobile payments. 1.1. Radio Frequency Identification (RFID) RFID was first patented in…

  • Cyber-Security

    information systems can face cyber-attacks on highway traffic controls systems, pipeline control systems, train control, and power/telecommunications. What is RFID? “RFID systems are relatively simple, consisting of readers and tags. Readers radiate a signal and receive responses from tags. Readers may operate in a number of frequencies.” There are two types of RFID tags, ones that are contactless and ones that are passive where the reader serves as power for the RFID tags. The most common…
