The Underestimated Magnetic Loop HF Antenna
www.nonstopsystems.comA magnetic loop antenna (MLA) can very conveniently be accommodated on a table top, hidden in an attic / roof loft, an outdoor porch, patio balcony of a high-rise apartment, rooftop, or any other tight space constrained location. A small but efficacious HF antenna for restricted space sites is the highly sort after Holy Grail of

Technical White Paper Massive MIMO for New Radio
images.samsung.comAn interesting aspect of the massive MIMO system is the active antenna that features a 2D planar array. A benefit that rises from the use of a 2D AAS is the ability to accommodate a large number of antennas without having to increase the deployment space. For example, when a uniform linear array system with 64 antenna

EE302 Lesson 13 Antenna Fundamentals.ppt
www.usna.eduA half-wave dipole antenna has a power gain of 1.64 (or 2.15 dB) over an isotropic source. Antenna gain relative to a dipole antenna can be expressed in decibels as dBd. Thus, an antenna with a gain of 3 dBd would have a gain of 5.15 dBi (3 dB + 2.15 dB) 10log (1.64) 2.15 dBi10 Actual Antenna Lengths
