1. A waveguide antenna system, comprising:
an electromagnetic, EM, transition portion comprising a transition region having a signal feed interface and an open waveguide section, the EM transition portion configured to couple EM energy from the signal feed interface to a guided waveguide mode of EM energy to the open waveguide section via the transition region; and
a leaky waveguide antenna portion configured and disposed to radiate electromagnetic energy received from the open waveguide section,
wherein the signal feed interface is disposed between a planar signal feed structure and the transition region, and
wherein the EM transition portion is electromagnetically coupled to the leaky waveguide antenna portion, the EM transition portion being configured to support a transfer of electromagnetic energy from a signal feed structure to the leaky waveguide antenna portion.
