Engineers often turn to VNAs to measure the return-loss characteristics of an antenna, but they must be used carefully ...

Dr. JeFreda R. Brown is a financial consultant, Certified Financial Education Instructor, and researcher who has assisted thousands of clients over a more than two-decade career. She is the CEO of ...

With an impressive low profile of just 0.047 times the low-frequency wavelength, the prototype presents an efficient radiation pattern, achieved simultaneously together with a 12:1 impedance ...

Abstract: A filtering transmitarray antenna (TA) based on a filtering antenna to filtering antenna (FA-FA) structure is proposed. The TA unit consists of two identical magnetoelectric (ME) dipoles ...

Then, the best-fitting polynomials are determined for different excitation modes. The antenna pattern of the base station is successfully reconstructed in an anechoic chamber by power measurements at ...

With new ATSC 3.0 broadcast technologies, anyone can enjoy HD and UHD TV for free with a capable antenna, but those living in rural areas stand to benefit the most. If the internet is terrible and ...

A Python-based Beamforming Simulator with a PyQt5 GUI for visualizing and analyzing antenna array patterns. Adjust parameters like the number of antennas, distance, delay, and frequency to generate ...
