Abstract: This paper introduces a dual-polarized spline-loop antenna element and array. The antenna element consists of two pairs of cross spline-ring dipoles, each with four thin metal strips ...

Amateur radio license exams typically have a question about the bandwidths taken up by various modulation types. The concept behind the question is pretty obvious — as guardians of the spectrum, ...

It has been 88 years since Earhart and Fred Noonan disappeared over the Pacific, but until now, the records of the search ...

Abstract: A method to estimate the current distribution on a dipole antenna is presented. A small double-output shielded loop probe is introduced as a magnetic field sensor to detect magnetic fields ...

Scientists at Tel Aviv University have proposed an intriguing way to peer into one of the most mysterious chapters in cosmic history — the “dark ages” of the Universe, a time before the first stars ...
