WebOn the basis of an 8 element (4+4) Delta Loop for 21 and 28 MHz, the Japanese amateur radio operator also developed a four-band Delta Loop model by adding to the first design 6 more elements (3+3) for 18 and 24 MHz. Later, 11 more loops for 144 MHz were added to the 14 el. four-band Delta Loop. WebApr 12, 2024 · The antenna comprises loop elements with quasi two-sources, and the effects of the element distance on the axial ratio bandwidth are revealed using the method of moments (MoM). It is found that the antenna has a maximum bandwidth of 41% at a distance of 0.15 wavelengths, three times as wide as that of an isolated loop element.
