The greater the number of turns the greater the directivity or antenna gain. The conductor width is not of great importance in the design. Find a tube with a circumference equal to one wavelength, and wrap wire in a helix spaced a quarter wavelength. Helical antennas, invented by John Kraus, give a circular polarized wave.
Helical Antenna Design Calculator Daycounter, Inc. Pasternack's EIRP Calculator determines the radiated power given the transmitter power, the cable loss to the antenna and the gain of the antenna.

Engineers can then export their antenna design to CST STUDIO SUITE for 3D simulation and integration into full system simulation. 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.

CST STUDIO SUITE is suitable for designing a wide range of antenna types, including horns, reflectors, wire antennas, printed antennas and arrays.Īntenna Magus is a software tool to help accelerate the antenna design and modelling process. These can be used to simulate antenna radiation patterns, installed performance and coupling in realistic environments. It also provides, given a beamwidth, the inner and outer radii of beam's coverage.ĬST Studio Suite® is an industry-leading EM simulation tool, with multiple solvers for suitable for a wide range of applications. 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. Rerun the model to observe reduction of 2.5 dB in the output received power due to the mismatch in antenna orientation.Antenna Downtilt and Coverage Calculator Pasternack

Select the Impedance button and then press the Update Block button to update the block. In the Antenna Properties panel of the Antenna Designer app, change Tilt to 30 degrees and the TiltAxis to. For example: Select the 'Edit Antenna' button in the Antenna_TX block mask parameter dialog box to reopen the Antenna Designer app. However, it is now possible to change the antenna properties and observe the effect on the output power in the model. This is since the original gain and impedance values used for the isotropically radiating antenna in the beginning were calculated from the same antennas and spatial settings. Run the model again, and note that the output power remained almost exactly the same. Azimuth is set to 180 degrees to align vector fields of the transmitter and receiver antennas.
– 90-degree elevation is chosen since the radiated signal that was transmitted in the positive z direction in the coordinate system of the transmitter, is now arriving from the negative z direction in the coordinate system of the receiver.
In the Antenna_RX block mask parameter dialog box, change the Direction of arrival to 180 degrees in azimuth and -90 degrees in elevation. Again, select the Impedance button and then press the Update Block button to update the block. To do so, in the Antenna Properties panel of the Antenna Designer app, set Tilt to 180 degrees. However, the receiving antenna needs to be rotated to face the transmitting antenna. Repeat the above steps to design Antenna_RX.
