SIST EN 300 631 V1.2.1:2003 is the Slovenian adoption of ETSI EN 300 631 V1.2.1, a European standard for point-to-point fixed radio antennas in the 1 GHz to 3 GHz band. It specifies antenna performance guidance for directional fixed-beam antennas used with new P-P systems, with emphasis on Radiation Pattern Envelope (RPE), Cross-Polar Discrimination (XPD), gain, polarization and conformance testing. It is intended for antenna suppliers, purchasers, operators and regulators who need a common basis for planning, procurement and verification.

What does SIST EN 300 631 V1.2.1:2003 specify?

SIST EN 300 631 V1.2.1:2003 specifies requirements and guidance for directional fixed beam antennas used with Point-to-Point (P-P) Fixed Radio Systems (FRS) in the 1 GHz to 3 GHz range. The document is organized into scope, references, definitions, frequency bands, antenna classification, electrical characteristics, conformance tests and an informative annex.

The scope excludes electronically steerable antennas and circularly polarized antennas. It also notes that a Regulatory Authority may set tighter requirements than the minimum values in the standard when spectrum use needs it.

What are the key requirements of SIST EN 300 631 V1.2.1:2003?

Frequency range and antenna type

Clause 1 limits the document to directional fixed beam antennas for new P-P systems operating in the 1 GHz to 3 GHz band. In practice, this means the standard is for fixed microwave link antennas, not for steerable or circularly polarized designs.

RPE-based antenna classes

Clause 5 groups antennas into three classes according to interference potential: class 1 for low, class 2 for medium and class 3 for high interference environments. Clause 6.1 then gives the RPEs for those classes, with figure 6 adding an elevation RPE for class 1. This helps planners match antenna sidelobe behavior to the radio environment.

Minimum XPD and gain

Clause 6.2 requires the XPD to meet or exceed the values in Table 1, and clause 6.3 sets minimum antenna gain in Table 2. For users, this means the antenna must satisfy both polarization purity and gain targets, not just one or the other.

Radomes and polarization

Clause 6.4 requires antennas with radomes to meet the same RPE and XPD limits with the radome in place. Clause 6.5 requires the antenna system to radiate a linearly polarized wave, either single or dual. In procurement and installation, this means the fitted radome and the chosen polarization must be considered part of the tested antenna system.

Conformance testing

Clause 7 says that EN 301 126-3-1 applies for antenna parameters. This gives manufacturers and test labs a defined route for checking antenna performance instead of using an open-ended test method.

Practical guidance in Annex A

Annex A gives guidance on environmental operation, wind survival, antenna stability, input connectors, VSWR, inter-port isolation and labelling. It is useful when the buyer and supplier need to agree on installation conditions, connector compatibility and identification.

What terms does SIST EN 300 631 V1.2.1:2003 define?

• Antenna - the part of a transmitting or receiving system designed to radiate or receive electromagnetic waves.
• Co-polar pattern - the radiation pattern measured with the test antenna and reference antenna similarly polarized.
• Cross-polar pattern - the radiation pattern measured with the reference antenna orthogonally polarized to the test antenna.
• Cross-Polar Discrimination (XPD) - the difference between the co-polarized main beam peak and the maximum cross-polarized signal over the stated angle range.
• Radiation Pattern Envelope (RPE) - the envelope below which the radiation pattern must fit.
• Radome - a dielectric cover that protects an antenna from the physical environment.
• Voltage Standing Wave Ratio (VSWR) - a measure used at the antenna input port to describe impedance match quality.

Who uses SIST EN 300 631 V1.2.1:2003?

Antenna manufacturers use this standard to design and describe point-to-point antennas for fixed radio links. Network operators, radio planners and system engineers use it when selecting antennas for local, regional and national networks, mobile base station connections, customer access links, telemetering and telecontrol.

Purchasers and quality managers use it to write technical requirements and compare supplier offers on a common basis. Regulatory authorities and frequency coordinators use it when assessing whether antenna characteristics suit the interference conditions in a band.

What changed in SIST EN 300 631 V1.2.1:2003 from the previous edition?

The foreword says this version was elaborated from EN 300 631-1 V1.1, and that the part originally foreseen as part 2 was separated for later publication as EN 301 525. The document history also shows earlier ETSI publication within the same family.

What does the SIST EN 300 631 V1.2.1:2003 document contain?

The document contains six figures for the RPEs of antenna classes 1 to 3 and the elevation RPE for class 1. It also contains two tables that set minimum XPD and minimum gain by class and figure.

Clause 3 provides definitions, symbols and abbreviations, while clauses 5 to 7 cover classification, electrical characteristics and conformance testing. Informative Annex A adds practical guidance on environmental performance, wind loading, stability, connectors, VSWR, isolation and labelling.
