Product details
Overview
RI-ANT-G04E from Texas Instruments is a low-frequency (134.2 kHz) gate antenna designed for RFID reader systems interfacing with TI HDX transponders. It delivers a focused read zone with typical inductance of 26 µH, operates from –30°C to +60°C, and features IP 44 ingress protection - distinct from the IP 65 rating of RI-ANT-G01E/G02E - making it suitable for indoor or sheltered industrial access control and asset management deployments.
For engineers reviewing the RI-ANT-G04E datasheet, RI-ANT-G04E pinout, RI-ANT-G04E application, or RI-ANT-G04E equivalent, key selection considerations include its 26 µH inductance at 134.2 kHz, IP 44 enclosure rating, 715 × 270 × 25 mm dimensions, 2500 g weight, and compatibility with TI's LF RFID reader/writers such as those used with RI-RFM modules.
Technical Context
The RI-ANT-G04E is a passive, resonant gate antenna optimized for 134.2 kHz HDX (High Data Rate eXchange) RFID systems. Its 26 µH inductance is tuned to match TI's standard reader output impedance and carrier frequency, enabling efficient energy transfer to passive transponders within its defined read zone.
Unlike the smaller RI-ANT-G01E and RI-ANT-G02E gate antennas, the RI-ANT-G04E uses a larger physical form factor (715 × 270 × 25 mm) and higher mass (2500 g), supporting extended-range detection in fixed-mount vehicle identification and container tracking applications where mechanical stability and field uniformity are prioritized over portability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LF RFID gate antenna applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-ANT-G02E | 27 µH inductance, IP 65 rating, smaller 200 × 200 × 25 mm footprint, 425 g weight. | Better suited for fully outdoor, washdown-prone locations due to IP 65; narrower read zone limits vehicle lane coverage. | Select RI-ANT-G02E when environmental sealing outweighs aperture size requirements. |
| RI-ANT-G01E | 27 µH inductance, IP 65 rating, compact 1018 × 518 × 47 mm dimensions, 745 g weight. | Offers largest aperture among IP 65 gate antennas but lower mass than RI-ANT-G04E - less stable in high-wind or vibration-heavy mounts. | Choose RI-ANT-G01E when both wide coverage and full environmental sealing are mandatory. |
Compared with RI-ANT-G02E and RI-ANT-G01E, the RI-ANT-G04E trades IP 65 protection for greater mechanical mass and dimensional stability - making it preferable where vibration resistance and consistent field geometry matter more than hose-directed water exposure.

FAQ
What is the operating frequency of the RI-ANT-G04E antenna?
The RI-ANT-G04E is designed exclusively for 134.2 kHz low-frequency RFID systems. Its 26 µH inductance is tuned to resonate at this frequency when paired with the appropriate matching capacitor in the reader circuit, ensuring maximum magnetic field coupling to TI HDX transponders. This frequency is standardized for animal identification and industrial tagging applications.
Does the RI-ANT-G04E include an integrated cable?
No, the RI-ANT-G04E does not include an integrated cable. It terminates in two spade/tongue terminals (7.5 mm width, 3.5 mm stud hole) intended for direct connection to the reader's RF output stage using externally sourced, impedance-matched coaxial cabling. Installation requires non-metallic clamps and M6.5 mounting hardware through pre-drilled holes.
What does IP 44 protection mean for the RI-ANT-G04E?
IP 44 indicates the RI-ANT-G04E is protected against solid objects larger than 1 mm (e.g., tools, wires) and water splashing from any direction. Unlike IP 65-rated variants (RI-ANT-G01E/G02E), it is not sealed against low-pressure water jets or dust ingress. This makes the RI-ANT-G04E appropriate for covered or sheltered installations - such as gatehouses or warehouse entries - but not fully exposed outdoor sites.
How does the RI-ANT-G04E differ from RI-ANT-G01E and RI-ANT-G02E?
The RI-ANT-G04E differs in three key ways: it has a lower IP rating (IP 44 vs. IP 65), higher inductance tolerance (26 µH vs. 27 µH), and significantly larger dimensions (715 × 270 × 25 mm) and mass (2500 g). These traits prioritize mechanical stability and field uniformity over environmental sealing - distinguishing it as a specialized option for vibration-sensitive or wide-aperture deployments where the RI-ANT-G04E delivers unique value.
Is the RI-ANT-G04E compatible with TI's RI-RFM reader modules?
Yes, the RI-ANT-G04E is explicitly designed for use with Texas Instruments' low-frequency RFID reader/writers, including the RI-RFM series. Its 26 µH inductance and terminal interface align with TI's reference designs for 134.2 kHz HDX systems. Integration requires proper impedance matching per TI's SCBS845 datasheet guidelines to ensure optimal power transfer and read range.
