Quasi-isotropic antennas are designed to deliver uniform radiation in almost all directions, thereby ensuring optimal signal coverage in complex communication environments. These antennas are pivotal ...

Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

When [Jephthai] wanted to build his own Yagi antenna, he turned to MMANA software for antenna modeling. This is an antenna analysis program that uses the moment method to calculate parameters for ...

GPU-accelerated electromagnetic simulation is redefining how engineers design and validate antennas in complex, electrically ...

Why there’s a need for a lightweight, easily reconfigured antenna. The clever and simple design devised by the researchers. Some aspects of performance evaluations in various configurations. Antennas ...

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 ...

The classic horn antenna undergoes some tough analysis and emerges with improvements that increase the frequency band to 3 GHz. The dual-ridged horn antenna (DRHA) is a workhorse in EMC and antenna ...

THE ANTENNA. This crucial component of any radio transmitting or receiving system has a history that actually predates the invention of radio itself. The first antennas were used by Princeton ...
