HCM Antenna Radiation Pattern Calculation

Calculate and optimize Antenna Radiation Patterns with HCM Pattern Optimizer

Optimize horizontal and vertical Antenna Patterns

The signatory states have agreed on the procedure for the combination of horizontal and vertical antenna patterns, within the framework of the HCM agreement.

HCM patterns or envelopes are a generalized picture of the existing irregular radiation pattern of a radio antenna. HCM Pattern Optimizer is a tool for calculating antenna envelopes based on the HCM Agreement. Antenna patterns of the manufacturers are converted into the optimal HCM pattern.  The software can calculate multiple horizontal and vertical HCM patterns for an antenna pattern. 

By combining HCM patterns, the levels of the same radio cell calculations lead to different field strengths (theoretical), which can lead to a situational optimization.


  • 360° antenna radiation pattern improvement
  • Improvement of current type of antenna radiation pattern
  • Concurrent modification of several antennas in tabs
  • Optional meta data can be saved together with antenna
  • Turning offset angles of antennas
  • Quick and easy screenshot feature available
  • Multilingual (currently German and English implemented)
