Observations of mean or average pulse profiles and their polarization give us much information on the shape of pulsar beams. The observed polarization variations, profile symmetry and frequency dependence of profile shape strongly suggest that the emission beam is conical and emitted from the vicinity of a magnetic pole.

Antennas have a decisive influence on the performance of wireless communication systems: depending on radiation characteristics, antennas differently affect cell coverage, multipath discrimination, and cochannel interference, which directly or indirectly impact on system performance.

Overview: We have limited most of our discussion throughout the text up to this point to the lowest-order Gaussian-beam wave and its limiting forms leading to a plane wave or spherical wave. In this chapter we want to briefly examine other beam shapes that may have important propagation characteristics for certain applications.
