Simulating a Super J-Pole: A 2m Antenna Analysis. This article describes a 5-element collinear antenna design for the 2m band, its radiation pattern, VSWR, and key components for optimal performance.

Delve into the virtual realm of an ingenious multiband omnidirectional dipole antenna. Explore its design intricacies through simulation.

The Loop on Ground (LoG): A compact receiving antenna with a cardioid-shaped radiation pattern, achieving directionality through clever grounding and monopole design.

Explore magnetic loop antennas, favored in ham radio. Learn about their dual loop design, coupling via induction, and AN-SOF Simulator for accurate simulations.

Struggling with complex helical antenna designs for LoRa & ISM? AN-SOF overcomes limitations of traditional methods, enabling accurate simulations of 433 MHz spring helical antennas.

Radiating towers or radio masts can be modeled in AN-SOF with a high degree of detail. This example shows a quarter-wave monopole antenna connected to a radial wire ground screen on a real ground plane.

The total length of the loop is about 0.4 wavelengths, so the current distribution shows a semi-cycle of a sine function.

Frequency sweep simulation of a receiving circular loop antenna. The loop is modeled using conformal segments, which exactly follow the contour of the antenna geometry.

The monopole is used for AM (Amplitude Modulation) radio transmissions. The far-field radiation pattern in the Fraunhofer zone is distorted due to the finite conductivity of the soil.

The antenna is composed of four vertical monopoles over ground. Each monopole is fed at its base by a voltage source of the same amplitude and phase as the others.
