Harvard researchers have discovered that cycads—one of the oldest living lineages of seed plants—heat up their reproductive ...

NASA lost contact with MAVEN during a routine Mars orbit. Discover what happened, why this orbiter is vital, and how recovery might succeed.

G will push antenna technology to new limits, demanding intelligent, adaptive, and multi-band systems capable of supporting ...

A research team has created a quantum antenna capable of precisely measuring terahertz frequency combs for the first time. A research team from the Faculty of Physics and the Centre for Quantum ...

Abstract: A high-gain, pattern-reconfigurable dielectric resonator antenna (DRA) with a switchable beam covering a 360° azimuthal plane is presented. It consists of a double-layer cylindrical ...

Abstract: This work presents a novel biconical antenna producing stable gain and radiation patterns in an ultrawide operating bandwidth. Conventional biconical antennas have ultrawide bandwidths, but ...
