ANT-433IBAR3-SMA

Antennas RF Overview

The RF Solutions ANT-433IBAR3-SMA is a compact, ground plane independent patch antenna designed for the ISM band. It operates at a minimum frequency of 433 MHz with a bandwidth of 6 MHz. The unit features a +3 dBi gain and includes a 2-meter RG174 connecting lead terminated with an SMA male connector. Its physical dimensions are 115 mm in length, 22 mm in width, and 5.5 mm in height.

Antennas RF Feature Summary

• Ground plane independent design allows flexible mounting without requiring a specific earth reference.
• Integrated 2-meter RG174 cable provides convenient connectivity via an SMA male interface.

Antennas RF Applications

• ISM band wireless communication systems
• UHF RFID reader installations
• Compact IoT sensor nodes

Antennas RF Procurement Notes

Verify that the SMA male connector polarity matches your receiving equipment's female port. Confirm the 2-meter cable length meets your installation layout requirements. Ensure the 115x22x5.5mm form factor fits within the designated enclosure space. Check that the 433 MHz frequency aligns with local regulatory allocations for your target region.

Antennas RF Selection Notes

Select this model when a low-profile, ground-independent solution is required for 433 MHz applications. The integrated cable simplifies assembly compared to bare PCB antennas. Consider the 3 dBi gain as standard for this form factor. Evaluate the 6 MHz bandwidth against your signal processing needs.

Antennas RF Part Context

This component belongs to the RF Solutions I-Bar series of patch antennas. It is specifically engineered for UHF and ISM band operations where space constraints prevent the use of larger whip or dipole antennas. The SMA interface ensures compatibility with standard coaxial transmission lines used in industrial and commercial radio setups.

Antennas RF Replacement Considerations

For direct functional substitution, consider the ANT-433WM3-SMA if a whip form factor is acceptable. The ANT-STUB-433SM offers a similar patch profile but may differ in cable specifications. Verify mechanical dimensions and connector types before swapping components to ensure fitment.
