Welcome to 'The Antenna Lab,' where we explore antenna concepts and simulations in a practical and intuitive way. Today is March 14th—Pi Day! What better way to celebrate than by demonstrating how a short dipole can have a radiation resistance of 3.14 Ohms?

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.

Experience versatile communication with this 5-in-1 J-Pole Antenna – your go-to solution for multiband excellence.

Discover the design and simulation of a multiband omnidirectional dipole antenna using AN-SOF. Operating at six key frequencies, this antenna combines closely spaced parallel dipoles into a single feed point. Explore how simulation reveals performance patterns and empowers your antenna experiments.

The Loop on Ground (LoG) antenna offers a compact solution for directional reception with a cardioid radiation pattern. This article explores its design and highlights the efficiency achieved through the Conformal Method of Moments (CMoM).

Explore dual-loop magnetic antenna design and simulation with AN-SOF. Model performance at five frequencies, showcasing radiation patterns, current distributions, and tuning values. Automated bulk simulations streamline the process.

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.

Center-fed half-wave dipole antenna at 300 MHz. The wavelength is close to 1 meter, so the dipole length equals 0.5 meters. 

Simulation of a folded dipole using curved wires at the dipole ends. The curved part is modeled exactly using conformal segments.

Frequency sweep simulation of a cylindrical dipole antenna. The results show how the current distribution along the wire approaches a sine function.
