SIST EN 301 215-2 V1.1.1:2003 is the Slovenian adoption of ETSI EN 301 215-2 V1.1.1. It specifies the essential electrical requirements for fixed beam antennas used with new Point-to-Multipoint (P-MP) systems in the 24 GHz to 30 GHz band, for central station and terminal station applications. In practice, it tells antenna suppliers, system designers, and test labs what radiation pattern and gain performance an antenna must meet before it is used in these P-MP systems.

What does SIST EN 301 215-2 V1.1.1:2003 specify?

SIST EN 301 215-2 V1.1.1:2003 covers directional and linear-polarized antennas for outdoor P-MP systems operating in the 11 GHz to 60 GHz family, with this part focused on 24 GHz to 30 GHz. It excludes electronically steerable antennas and circularly polarized antennas, so it is aimed at fixed-beam antenna designs.

The document is organized into Scope, References, Definitions, Symbols and Abbreviations, and Electrical characteristics, followed by Bibliography and History. Clause 4 is the technical core and sets the antenna performance templates and gain limits used for compliance and design checks.

What are the key requirements of SIST EN 301 215-2 V1.1.1:2003?

Clause 1 limits the document to linear polarization and fixed beam antennas used with new P-MP systems, including central station and terminal station applications. That means the antenna choice has to match this operating model before any pattern or gain values are checked.

Terminal station antennas

Clause 4.1 sets the terminal station antenna limits. The terminal station radiation pattern envelope (RPE) applies to both horizontal and vertical linearly polarized antennas, and class TS1 has the required copolar and crosspolar envelope in Figure 1 and Table 1. Clause 4.1.2 also requires a minimum boresight gain of 26 dBi for class TS1, which matters because terminal links need enough forward gain to support the planned coverage and link budget.

Central station sectored antennas

Clause 4.2 defines central station sectored antenna templates for class CS1 and class CS2. The supplier has to declare the sector angle, and the gain values are judged relative to the maximum gain in that declared sector. In practice, this is how a manufacturer shows that a sector antenna fits the intended cell width while controlling unwanted radiation outside the sector.

Clause 4.2.2 adds a minimum boresight gain requirement for sectored central station antennas as a function of sector angle. This means the antenna must keep enough forward gain as the sector gets wider, so network planners can balance coverage area and interference control.

Elevation pattern, polarization, and radomes

Clause 4.4 defines a symmetric central station elevation RPE and explains how electrical tilt and mechanical tilt are handled. This is important for base-station deployment because the antenna may need downtilt to match terrain and cell coverage.

Clause 4.5 requires linear polarization for both terminal station and central station antennas. Clause 4.6 requires antennas with radomes to meet the same absolute gain and radiation pattern values with the radome fitted, so the cover cannot degrade the antenna beyond the stated limits.

Clause 4.3 notes that no omni-directional central station antennas have been identified in this part. For buyers and designers, that means the technical focus here is on sectored and terminal antenna behavior rather than omnidirectional coverage.

What terms does SIST EN 301 215-2 V1.1.1:2003 define?

Point-to-Multipoint (P-MP) is the system arrangement where one central station serves multiple remote terminals. It is the operating model that the antenna requirements are written for.

Radiation pattern envelope (RPE) is the allowed limit shape for antenna radiation in azimuth or elevation. It tells you how much energy the antenna may radiate away from the desired direction.

Terminal station (TS) is the end-site antenna used in the P-MP network. In this document, TS antennas have their own class and gain limit.

Central station (CS) is the base or hub antenna serving the network. The document gives separate rules for sectored CS antennas and their elevation patterns.

Boresight is the main beam axis of the antenna. Boresight gain is the forward gain in that main direction and is a key planning value.

Radome is the protective cover over an antenna. The standard requires performance to remain within limits even when the radome is installed.

Who uses SIST EN 301 215-2 V1.1.1:2003?

Antenna manufacturers use this standard when designing TS and CS antennas for 24 GHz to 30 GHz P-MP systems. They use it to shape the radiation pattern and confirm boresight gain.

Network designers and operators use it when selecting antennas for outdoor fixed radio links. It helps them match sector width, tilt, and polarization to the planned site layout.

Test laboratories and certification bodies use it to check radiation pattern envelopes, gain, polarization, and radome effects. Procurement teams use it to compare antenna offers on the same technical basis.

Which standards are used with SIST EN 301 215-2 V1.1.1:2003?

ETSI EN 301 215-1 provides the general aspects for this antenna family, and this part with Part 1 forms the EN for the 24 GHz to 30 GHz range.

ETSI EN 301 213-1 gives the basic parameters for Point-to-Multipoint equipment in the 24.25 GHz to 29.5 GHz range.

ETSI EN 300 833 gives minimum requirements for point-to-point antennas and is used when a high-gain P-MP antenna follows point-to-point antenna performance.

What does the SIST EN 301 215-2 V1.1.1:2003 document contain?

The document contains the radiation pattern templates in Figures 1 to 5 and the class tables for TS1, CS1, and CS2. It also gives the minimum boresight gain rules and the way the sector angle is used in the central station limits.

Clause 4.4 provides the elevation pattern guidance and explains how tilt shifts the pattern in practice. Clause 4.6 explains how radomes are treated in the compliance check.

The document is written for design and verification work rather than for general theory. Its tables and figures are the parts used in engineering reviews, antenna measurement, and conformance testing.
