A circular patch antenna based on open elliptical-ring slots and shorting vias with conical radiation patterns is proposed. Fed by the coaxial probe at the center of the circular patch, the proposed ...

Small ceramic patch elements offer nearly perfect single-frequency receive characteristics and have become the standard for GPS L1 antennas. However, the new generation of GNSS receivers now being ...

This is a very technical question. Since I am not an RF engineer, I reached out to a few people for the answer. Before I provide an answer, let me explain what the terms mean, for those who don’t know ...

Antennas are a key component to any RF gadget. But antennas often only perform well over a narrow band of frequencies. For some applications, this is acceptable, but often you would like to ...

I am not an engineer, but I will offer an answer below. Any of our readers are invited to provide further clarification. A circular-polarized antenna is used to read tags in random orientation. The ...
