Engineers might design a fabulous new wireless device only to fall into the trap of poor antenna design or placement. I've heard stories about designers who place GPS-receiver antennas in metal boxes, ...

Tests on this prototype antenna are scheduled to wrap up soon; however, researchers plan to return to the ETR in 2020 to conduct additional tests on Europa Clipper’s high-gain antenna flight ...

Voltage standing-wave ratio (VSWR) measurement and control is another popular application in high-power RF amplifiers. Impedance mismatches (high VSWR) at the antenna cause reflections and lead to ...

Set up the antenna in the middle of the field, have it transmit some RF, and measure the signal strength at points along a series of radial lines away from it I’d end up with a spreadsheet, from ...

Allystar Technology Co. Ltd., headquartered in Shenzhen, China, is offering new patch antennas: the AGR6302 and AGR6303.Both GNSS antenna models are designed for precision dual-frequency positioning.

The antenna consists of low- and high-band array antennas, positioned back to back, each equipped with a reflector screen, allowing WBCQ to access all shortwave frequency bands between 6 MHz and 26 ...

Radio-frequency (RF) test-and-measurement instruments such as high-bandwidth oscilloscopes and RF digitizers use RF sampling analog-to-digital converters (ADCs) that simultaneously digitize ...

Guerrilla RF, Inc. (OTCQX: GUER) announces it is now sampling the GRF5123 and GRF5124, two new high gain, high linearity driver amplifiers designed specifica ...

This week, the telescope turned on its high-gain antenna, which enables to telescope to send data to Earth and receive commands via NASA’s Deep Space Network.
