Design of antenna feed with amplified power distribution using groove-gap waveguide technology

The design of an antenna feed system that includes amplification of the signal is presented. The feed includes power division (in this initial example a 1 to 2 division is shown) and the amplification section. The design is made in the groove gap waveguide technology in the X band and can be easily scaled to millimeter frequency bands. Besides the manufacturing advantages of groove gap waveguide when compared to conventional rectangular waveguide, this design includes the packaging of the MMIC amplifier by using the same gap waveguide technology, thus providing a robust solution.
