  • Designing Loop Antennas for the rfPIC12F675
    This application note describes the design of a singleended loop antenna for rfPIC12F675 transmitters. The PCB design will cover all 3 frequency bands from 290 MHz through 930 MHz with a few component value changes The previous Microchip RF transmitters had balanced outputs which required twice
  • Matching Small Loop Antennas to rfPIC(TM) Devices
    In close proximity to the human body, small loop antennas outperform small dipole and monopole antennas [1]. Their size, robustness and low manufacturing cost have made small loops the most popular antenna for use in miniature key fob transmitters. A small loop antenna typically consists
  • AN-00500 - Antennas: Design, Application and Performance
    for the three most common low-power antenna styles, the whip, helical and loop trace.
  • RFID Coil Design
    . Alternatively, a small loop antenna coil that is resonating at the frequency of the interest (i.e., 125 kHz) is used. This type of antenna utilizes near field magnetic induction coupling between transmitting and receiving antenna coils.
  • AIRDATA LAUNCH FAST, PORTABLE INTERNET ACCESS USING COBHAM'S ANTENNAS
    works in a similar way to WiFi but without the usage fees. This has been made possible by a wireless local loop network built by AIRDATA that allows both voice and data transmission. The network uses a system that is based on worldwide harmonised 3G radio standards. Compared to wireless LAN
  • Phase Conjugate Laser Optics - Preface
    are now routinely used to focus high-energy densities on a. surface. This ability also opens new opportunities in basic science interactions for. plasma physics or X-ray generation with sources delivering ultrashort pulses. Also. due to the directivity of optical antennas, lasers will undoubtly
