Antenna Downtilt and Coverage Calculator Pasternack

Pasternack

The Antenna Downtilt and Coverage Calculator (aka Antenna Tilt Angle Calculator) is used to determine the approximate downward angle, measured in degrees, which the transmitting antenna is to be positioned for optimal signal strength and coverage. It also provides, given a beamwidth, the inner and outer radii of beam's coverage.

CST antennaCST STUDIO SUITE

CST

CST STUDIO SUITE® is an industry-leading EM simulation tool, with multiple solvers for suitable for a wide range of applications. These can be used to simulate antenna radiation patterns, installed performance and coupling in realistic environments. CST STUDIO SUITE is suitable for designing a wide range of antenna types, including horns, reflectors, wire antennas, printed antennas and arrays.

Antenna Magus is a software tool to help accelerate the antenna design and modelling process. It increases efficiency by helping the engineer to make a more informed choice of antenna element, providing a good starting design tuned to the specifications of the application. Engineers can then export their antenna design to CST STUDIO SUITE for 3D simulation and integration into full system simulation.


EIRP Calculator Pasternack

Pasternack

Pasternack's EIRP Calculator determines the radiated power given the transmitter power, the cable loss to the antenna and the gain of the antenna.

Helical Antenna Design Calculator 

Daycounter, Inc.

Helical antennas, invented by John Kraus, give a circular polarized wave. They are one of the easiest to design. Find a tube with a circumference equal to one wavelength, and wrap wire in a helix spaced a quarter wavelength. The conductor width is not of great importance in the design. The greater the number of turns the greater the directivity or antenna gain. Receiving and transmitting antennas must be wound in the same direction, since the wave is polarized.

Whip Antenna Design Calculator

Daycounter, Inc.

A whip antenna also known as a monopole antenna looks capacitive if it is shorter than a quarter wavelength, and is tuned to resonance with a series inductor. PCB antennas are often shorter than a quarter wavelength due to board size restrictions and often fit into this category.

COMSOL Multiphysics®

COMSOL COMSOL

The RF Module, an add-on product to the COMSOL Multiphysics® simulation software, enables engineers to analyze RF, microwave, mmWave and THz designs in multiphysics scenarios. The software includes application libraries featuring a variety of antenna examples such as a microstrip patch antenna array used as transceivers of radar and RF signals. The libraries also include: dipole, biconical, and log periodic antenna, parabolic reflector, slot antenna and PIFA, state-of-the-art models such as fractal, substrate integrated waveguide, two-arm helical antenna, double ridged horn, corrugated circular horn antenna and so on. The RF module allows for the computation of antenna impedance matching, far-field radiation pattern, gain and directivity, and can be extended to include other physics phenomena, such as structural deformation induced by temperature change.
