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, ...

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical ...

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 ...

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 ...

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 ...

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.

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 ...
