### BASICS Of ANTENNAS

Antenna Beam Solid-Angle We now know that the beam solid angle is given as Some power is radiated by the side lobes. Thus the solid angle ΩM of the main lobe is less than the beam solid angle ΩA (varies from <100% to 75% of ΩA). Thus we introduce a factor kB in following equation: 4 A n HP HPP d( , ) π Ω = Ω≈∫∫θφ θ φ main lobe
