Journal of Electromagnetic Waves and Applications Vol. 29, № 13. P. 1720-1727Abstract: The modified waveguide-fed dipole-like antenna is designed using the induced emf method. To excite the antenna arms, the two equal in magnitude and 180° and outofphase excitations are created using the standard rectangular waveguide. Since the area around the radiating arms is free of any conductors (exception for a finite ground plane), the antenna radiation is of high polarization purity. The stand-alone antenna operating near 1.7 GHz was fabricated and tested to verify the design validity. Both the far-field pattern and the return loss level show good agreement with the designed parameters. Such antenna is optimal for using as a building block in the linearly polarized assemblies as well as the stand-alone radiators.
