2. Antenna Types

  Rectangle Horn Antenna [ANT01]   23dBi Standard Rectangle Horn Antenna[ANT02]
  Rectangular waveguide type rectangular horn antenna with gold plated inside.   Rectangular waveguide type standard horn antenna with 23dBi antenna gain, gold plated inside.


  Minute Loop Antenna[ANT06]   30° Conical Horn Antenna [ANT03]
  Used when irradiating microwaves or millimeter waves onto a small area with non-contact, or when measuring the electric field strength distribution finely.   Conical horn antenna with a rectangular waveguide, and the inside is gold-plated.


  Double Ridge Horn Antenna [ANT14]   Circularly Polarized Wave Antenna for 5.8GHz [ANT13]
  Since a double ridge waveguide is used for the feeding part, it can be used in a wide band.   Both right-handed circularly polarized waves and left-handed circularly polarized waves are supported.


  Omni Antennas[ANT04]   50GHz band, Omni Antenna [ANT17]
  Omni-type antenna that can send and receive over 360 degrees.   This is a waveguide-fed omni-directional antenna in the horizontal plane.
Equipped with a radome, it can be used outdoors.


  EMI Measurement Antenna [ANT46]   W-Band Lens Antenna [ANT18]
    A high gain antenna with a simple configuration. We can also develop a beam transmission system using two lenses.


  Metal Waveguide Probe Antenna [ANT61]   Fermi Antenna [ANT88]
  The tip of the rectangular waveguide is a probe antenna.   This is a printed plate antenna with a wide frequency bandwidth of 100%.
Ideal for UWB applications.


  Millimeterwave convergence antenna [ANT05]   Microstrip antenna for 24GHz band [ANT16]
  Used for non-contact irradiation of millimeter wave to small area of millimeter wave detectors. It has characteristics of high radiation efficiency and low reflection attenuation, and can irradiate a small area at the wavelength level.   A flat type antenna that is thin and lightweight due to the microstrip array method.


  Cassegrain Antenna [ANT19]   Phased Array Antenna [ANT40]
  Extremely small blocking and higher gain.   We design and manufacture a variety of phased array antennas.


  Monopole Antenna [ANT22]   Dipole Antenna [ANT23]
    VHF frequency band.
Omni-directional in horizontal plane.


  Log-periodic Antenna [ANT24]   Aircraft-mounted Antenna [ANT25]
    ・Reliable performance in harsh environment.
・It's possible to customize
