The FCC TVStudy OET-69 software includes the ability to run studies using actual antenna azimuth and elevations patterns, but it wasn’t until release of Version 1.2.8 that there was a way to apply ...

If you’ve ever worked at a station that’s installed a new antenna, you’ve probably wondered how well the antenna’s real pattern matched the nice clean pattern supplied by the antenna manufacturer. The ...

The FCC has released the details of its order allowing FM broadcasters to use computer modeling to verify directional antennas. It also explained why it didn’t adopt several proposals that were in the ...

No audio available for this content. More satellites, more constellations, more multi-frequency receivers — they all drive greater achievable accuracy. But they also raise the requirements on GNSS ...

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 ...

No audio available for this content. Partnering with the U.S. Coast Guard Navigation Center (NAVCEN), U.S. Space Force and Lockheed Martin Space have released the GPS IIR/IIR-M satellite antenna ...

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 ...

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 ...

An overview of antenna design considerations is presented. The design considerations include system requirements, antenna selection, antenna placement, antenna element design/simulation, and antenna ...

Placing an antenna in a design always needs care, but when there are two or more antennas in the design, it is even more important to understand how the antennas radiate, how they will perform ...
