Receiving a signal from a geosynchronous satellite 22,300 miles out or a GPS satellite over 10,000 miles away is a challenge. Big gain antennas usually are necessary. But that’s just the opposite of ...
An introduction to properties of individual antennas and arrays of antennas. Retarded potentials, dipoles of arbitrary length, radiation pattern, gain, directivity, radiation resistance. The loop ...
This blog discusses several challenges behind developing mmWave radar systems for the next generation of smart cars and trucks and looks at new capabilities recently added to electronic design ...
Global navigation satellite system (GNSS) technologies such as global positioning system (GPS), GLONASS, COMPASS/Beidou, Galileo, QZSS, IRNSS/NavIC, and others are increasingly crucial for terrestrial ...
Building antennas is a time-honored ham radio tradition. Shortwave antennas tend to be bulky but at VHF frequencies the antenna sizes are pretty manageable. [Fjkaan’s] 2 meter quadrifilar helicoidal ...
