Title: **Innovator Mitsuhiro Kusano: Pioneering Advances in Antenna Technology**

Introduction

Mitsuhiro Kusano, an influential inventor based in Tokyo, Japan, has made significant contributions to the field of antenna technology. With a total of two patents to his name, Kusano is recognized for his innovative solutions that enhance the efficiency and performance of microwave antennas.

Latest Patents

Kusano's latest patents showcase his groundbreaking work in radio frequency technology. The first patent details a **horn antenna with a choke surface-wave structure on the outer surface**, which features a plurality of axially spaced radial fins mounted on the horn's outer surface. This unique configuration forms several radial grooves and a front axial groove, all designed with depths nearing a quarter wavelength of the microwave being utilized. The incorporation of these fins and grooves establishes a choke surface-wave structure, significantly improving the radiation pattern while minimizing undesired radiation and side lobes. Notably, this design allows for the efficient radiation or reception of two different frequency waves using a single horn antenna, characterized by reduced side lobe and excellent cross-polarization features.

Another significant invention is the **shaped beam reflector antenna**, which comprises a main reflector and a feed horn for directing electromagnetic waves. The main reflector features a unique configuration consisting of a central section with multiple torus reflector segments, alongside horizontal side end sections that contain parabolic reflector segments. This innovative design divides the reflector segments into symmetrical and asymmetrical groupings, enhancing the maximum radiation direction of beams reflected from both the symmetrical and asymmetrical portions of the antenna.
