Presenting a formidable challenge, the creation of an omnidirectional antenna with the capability to function across diverse frequency bands from a singular feed point demands innovative engineering.
The image below illustrates a simulated multiband dipole, which is a composite of five closely spaced parallel dipoles. Converging at the antenna’s center, these dipole extremities meet at a shared feed point. Each dipole spans approximately half a wavelength, yielding resonance frequencies of 3.7, 7.05, 14.2, 18.1, 21.2, and 28.5 MHz. The radiation pattern animation showcases the emergence of a donut-shaped omnidirectional pattern at lower frequencies, evolving into a more intricate lobed pattern as frequencies ascend.
This exemplifies a scenario where the indispensable utility of a simulation tool like AN-SOF comes to the forefront. AN-SOF exhibits an exceptional ability to simulate closely spaced wires, a feat that is often challenging. The remarkable capability of AN-SOF can be attributed to its implementation of a calculation method that triumphantly overcomes the seven key limitations prevalent in traditional methods. These intricacies are thoughtfully detailed in this article, highlighting the innovation driving AN-SOF’s prowess.
