Firstly, an approach is presented to increase band-width of HF RFID reader antennas to improve the reception of sub-carrier frequencies. A fabricated enhanced band-width antenna at 13.56 MHz is evaluated for its capability in being ... S Soodmand - 《University of Surrey》 被引量: 0发表: ...
Or take our AX-81S active HF antenna: Originally designed as a ruggedized marine antenna, it has become popular for general shortwave applications due to its low cost, small size and high performance. With excellent dynamic range and low noise, this may well be the ideal shortwave antenna ...

THIS PAPER PRESENTS THE DESIGN OF TWO TAG ANTENNA MODELS THAT CAN BE INTEGRATED INTO A 13.56 MHZ HF RFID SYSTEM. IN ORDER TO VERIFY, THE PERFORMANCE OF THE TWO TAG ANTENNA MODELS PROPOSED A SERIES OF SIMULATIONS USING THE ANSOFT HFSS APPLICATION WERE PERFORMED. THE ADVANTAGES OF USING THESE ...
This paper presents the design of a HF antenna integrated within aircraft Vertical Tail Plane (VTP) by using virtual prototyping. The design task is carried out with a numerical solver based on FDTD which was validated for analysis but also for design and optimization purposes. An accurate virtua...
The design of an antenna for NFC tags and dynamic NFC tags consists of designing a well-suited antenna loop placed either on or within the support material of the tag label or on the application pc-board. Its impedance matches the device’s internal tuning capacitance value (Ctuning)...
