Discover the perfect balance: a simple dual-band vertical dipole, AN-SOF modeling, and real-world results. Elevate your ham radio experience.

Discover the vital role of historical theoretical results alongside advanced numerical calculations in accurately approximating current distribution on linear antennas.

This article validates AN-SOF’s results against the IEC FDIS 62232 standard by replicating an RBS panel antenna model with nine dipole radiators. The successful validation highlights AN-SOF’s ability to deliver highly accurate results, even with relatively simple models.

Moving beyond the uniform-current simplifications of small antennas, this article analyzes the electromagnetic behavior of electrically large circular loops. By benchmarking AN-SOF numerical results against classical Fourier theory, we explore how loop circumference and wire thickness influence non-uniform current distributions, parallel/series resonances, and axial directivity. This detailed study validates the accuracy of CMoM for curved radiators.

Validate the precision of the Conformal Method of Moments (CMoM) through this rigorous study of small loop antennas. By comparing simulated circular and square loops against classical asymptotic theory, we demonstrate how AN-SOF accurately models radiation resistance and directivity in the low-frequency limit, where antenna size is a tiny fraction of a wavelength. This article provides essential insights into shape-independence and numerical stability for electrically small radiator design.

Overcome probe inductance and simplify your antenna designs with capacitive feeding. This study demonstrates how to utilize proximity coupling to achieve a perfect 50-Ohm match and 10 dBi gain. Validated against classic experimental benchmarks, our simulation shows how internal reactance cancellation enables wideband performance in microstrip patches without external matching networks.
