RF Designs and Simulations

RFID stands for Radio-Frequency Identification. The RFID device provides a unique identifier for that object and just as a bar code or magnetic strip the RFID device must be scanned to retrieve the identifying information. More Detail: Microstrip and Printed Antenna Design

The helix antenna is a travelling wave antenna, which means the current travels along the antenna and the phase varies continuously. Helix antennas (also commonly called helical antennas) invented by John Kraus give a circular polarized wave.  Helix antennas are referred to as axial-mode helical antennas. The benefits of this helix antenna are it has a wide bandwidth, is easily constructed, has real input impedance, and can produce circularly polarized fields. There are two mode of circular polarization in helix antenna. Left handed helix antenna:  In left handed helix antenna if you curl left hand fingers around the helix, thumb would point up. The waves emitted from this helix antenna are Left Hand Circularly Polarized. Right handed helix antenna:  In right handed helix antenna if you curl right hand fingers around the helix, thumb would point up. The waves emitted from this helix antenna are Right Hand Circularly Polarized The minimum number of t...

USB ( Universal Serial Bus ) is the most popular connection used to connect a computer to devices such as digital cameras, printers, scanners, and external hard drives.  USB  is a cross-platform technology that is supported by most of the major operating systems. UART is a computer hardware device that translates data between parallel and serial forms ( SerDes ). A dual UART (Universal asynchronous receiver/transmitter), or  DUART , combines two UARTs into a single chip. The universal asynchronous receiver/transmitter (UART) takes bytes of data and transmits the individual bits in a sequential fashion. At the destination, a second UART re-assembles the bits into complete bytes. Each UART contains a shift register, which is the fundamental method of conversion between serial and parallel forms. Serial transmission of digital information (bits) through a single wire or other medium is less costly than parallel transmission through mult...
