Frequently asked questions


Technical questions - general


What is RF technology?

RF-technology is the branch of electrical engineering and includes areas of radio and television technology, antenna technology and the transmitting and receiving equipment.

What frequency range covers the high frequency technology?

In high-frequency technology, the frequency range of about 30 kHz to 300 GHz extends. Components and assemblies sizes lie roughly in the order of a wavelength.

What special features characterize the high frequency technology?

In the high frequency technology components no longer respond as expected. There are added features such as parasitic capacitive and inductive losses. Moreover, the realization of circuits with discrete components is no longer possible at high frequencies. That is why the use of new components is as SMD, waveguide or microstrip lines, and for example, the replacement of coils and resistors by lines required.

What are the application areas of high frequency technology?

The RF technology is in communications technology used, for example, in the preparation, processing and transmission (wireline or wireless) analog and digital signals at the hardware level. Especially in the wireless transmission of data and information such as the radio, TV, mobile and satellite communications, wireless, positioning and navigation (radar, GPS) and on printed circuit boards in electronic devices is the high frequency technology its application. Further fields of application are the basic research in physics, material testing (RF signals feel fine cracks in conductive materials, automated and non-destructive testing), heating (microwave oven), identification (RFID), medicine (magnetic resonance imaging).

In which frequency range the ANTONICS antennas are located?

ANTONICS covers with its antennae an area of ​​approximately 130 MHz - from 6 GHz. The most important frequency bands are: 2m band, TETRA, LTE, GSM, UMTS, GPS, GLONASS, Wi-Fi.

Technical issues for professionals
 

How large the distance between two antennas must be another?

As the effect of the two antennas is dependent on many parameters, can this be no universal answer. To achieve a good decoupling of two antennas, the distance based on the lowest frequency f and thus maximum wavelength λ should be as a guideline 2-3 λ. Ideally, a measurement should be carried out, in which the return loss and the isolation between the antennas, and the directivity characteristics can is determined.

Do I need a ground plane and if so, how big should this be?

A ground plane, also called the counterweight, is a conductive, usually made of individual existing wires surface, which simulates the conducting earth, if this is due low-conductivity or its distance to the antenna too large. A ground plane is not necessarily connected to ground. It leads to the reflection of the radiation. Antenna and ground plane must be coordinated, taking into account the dimensions and the electrical conductivity of the ground plane, because the geometry and dimensions of the ground plate have a decisive influence on the radiation pattern of the antenna. A ground plane should be in the radius of at least λ / 4 or larger. In addition, the properties of the ground plane depend on the electrical conductivity of the material used.

At which point the train antenna should be best positioned?

To ensure an omnidirectional radiation, an antenna should be centrally located on the vehicle roof. This allows a clear view on all sides. In reality, there are often obstacles (eg. air conditioning) that limit the all-round radiation. Then, the antenna can be mounted above on a platform. Depending on the installation options the distance to metallic elements according to the rule should be at least 3 λ.

Which frequency bands and how many radiators can I use in an antenna?

In principle there are no restrictions. However, in order to ensure sufficient decoupling between two radiators, the radiators should comply with interval rule (2-3 λ) and not overlap in the frequency range or have directly adjacent frequency ranges.
