This communication presents a Fabry-Pérot resonator antenna (FPRA) with the dual-band dual-orthogonal circular polarization (CP). The whole FPRA consists of a linearly polarized (LP) microstrip patch ...

Two novel microstrip patch antennas with multiple parasitic patches and shorting vias have been presented for the bandwidth enhancement. Based on the conventional triangular patch antenna, two more ...

RAKwireless WisMesh Board ONE allows users to create custom Meshtastic nodes with optional OLED, GPS, antennas, battery, and enclosure.

Scientists are trying to solve a decade-long mystery by determining the identity of anomalous signals detected from below ice in Antarctica.

Space ‘Bunch of SCARS’: Space Force’s Hammett speeds phased array antenna integration " [T]his capability is so important to where we're headed in the next couple of years, with having the ...

In addition, the authors made no comparison with the performance parameters between the reference antenna and the proposed antenna. In [9], the authors proposed a rectangular patch microstrip antenna ...

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect ...
