Pillbox Antenna Design and Simulation
A pillbox antenna is a linearly polarized cylindrical reflector embedded between two Parallel plates. It is usually fed by a waveguide. The pillbox is part of a family of antennas […]
Helical Filter Design
A helical bandpass filter consists of a series of cavities that are magnetically coupled together by an iris in each wall. Each cavity consists of a coil soldered to ground […]
RFID Tag and Reader Antenna Design
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 […]
High Signal Quality in PCIe Gen3 Channels
The increased data rates of today’s high-speed Input/ Output (I/O) buses make maintaining transmission channel signal quality all the more challenging. One reason for the challenge is the parasitic effects […]
Helix (Helical ) Antennas Design using EM Solver
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 […]
