ETRA4503P

RF Antennas

The ETRA4503P antenna is a largely multipurpose antenna, suitable for various application fields. This antenna is a full circular-polarization patch antenna providing more than 10 dBic gain, making it ideal for a number of applications. It’s antenna type is defined as a 2-axis tilt, tilt-level, and rotationally symmetric antenna. This means it can be used in situations where higher gain is needed and where either polarization angle or tilt can slightly be adjusted as part of the antenna setup and usage.

Application Fields

The ETRA4503P antenna is highly viable for both base station antennas and interior antennas. It can be used in such applications in a number of industries, including medical, agriculture, and Autonomous Vehicle-related. The ETRA4503P is particularly useful for medical applications, due to its ability to provide high gain in environments with limited space. This makes it perfect for small hospitals, nursing homes, or even home care situations, where unobtrusive antennas may be necessary.

Agriculture is another application field that can benefit from the ETRA4503P. Its gain and orientation versatility make it ideal for transmitting information from farms and greenhouses, as well as for providing Wi-Fi and cellular access for agricultural workers. The antenna has similar versatility in Autonomous Vehicle applications. Its ability to adjust polarization angle or tilt allows it to be used for signal monitoring and receiving, as well as for transmitting data in and between autonomous vehicles.

Working Principle

The ETRA4503P antenna works by utilizing an arrangement of printed elements on both sides of an insulated dielectric substrate. Two conductive circular patches are printed on each side of the dielectric, intertwined with each other, and connected via microstrip lines. This arrangement allows for the antenna to be rotated and tilted, enabling for enhanced gain at all operating angles.

The ETRA4503P is typically used in a two-axis tilt configuration. The two axes, roll and pitch, are independently adjustable and can be used to optimize the antenna’s gain for a given location. In this configuration, the antenna offers a gain of up to 10 dBic and a far-field pattern that is almost circular in nature.

Conclusion

The ETRA4503P antenna is a great option for a variety of application fields, including medical, agriculture, and Autonomous Vehicle-related. This antenna type brings together roll and pitch orientation, providing a gain of up to 10 dBic, and an almost circular far-field pattern. By its nature, the antenna is highly versatile, allowing for use in a number of scenarios where increased gain is needed.
