2. Products Line-up

  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.


Rectangular waveguide antennas are used at relatively high frequencies to transmit electromagnetic waves through the waveguide.


  Double Ridge Horn Antenna [ANT14]   Circularly Polarized Wave Antenna for 5.8GHz [ANT13]

Double ridge horn antenna uses a double ridge waveguide for the feeding part, so that they can be used over a wide bandwidth and is suitable for measuring antenna patterns.


Circularly polarized waves are often used in satellite communications, and also have characteristics that make them less susceptible to unwanted reflection of radio waves from the surroundings (multipath).


  Omni Antennas[ANT04]   50GHz band, Omni Antenna [ANT17]

Omni-type antenna that can send and receive over 360 degrees.


Omni-antennas are omni-directional and are used for communications over relatively short distances.KEYCOM's product is waveguide-fed and omni-directional in the horizontal plane and is equipped with a radome, fit for outdoor use.


  EMI Measurement Antenna [ANT46]   W-Band Lens Antenna [ANT18]

KEYCOM has a variety of antennas specialized for EMI measurement, such as Dipole antennas, Biconical antennas, Log-peripheral antennas, Horn antennas etc., to support your effective and efficient EMI testing.


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]

This is a rectangular waveguide with a probe antenna attached to the tip.


Fermi antenna is an antenna made on a printed circuit board. It has a broadband feature with a frequency specific bandwidth of 100%, making it ideal for UWB (Ultra Wide Band: Ultra Wide Band wireless communication).


  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.


Microstrip antenna is a type of planar antenna in which the radiating elements are patterned on a dielectric substrate. It contributes to developing thinner and lighter devices.


  Cassegrain Antenna [ANT19]   Phased Array Antenna [ANT40]

Cassegrain antenna is a type of parabolic antenna.

The difference between both anntennas is that Parabolic antenna consists of a primary reflector and a primary radiator on the opposite side.


We design and manufacture a variety of phased array antennas.


  Monopole Antenna [ANT22]   Dipole Antenna [ANT23]

Monopole antennas is one of the most basic types of antennas, with one side of the dipole antenna connected to the ground plane. It is used in relatively low frequency bands, with its size smaller than a dipole antenna.


Dipole antenna is one of the most basic types of antennas. The antenna length becomes 1/2λof wavelength. It is used in relatively low frequency bands.

When installed vertically, it can transmit and receive signals in all horizontal directions. It is also called a half-wavelength dipole antenna.


  Log-periodic Antenna [ANT24]   Aircraft-mounted Antenna [ANT25]

Log-periodic antenna consists of many elements. It has sharp directivity and a wide frequency range.

Although it looks similar to Yagi antenna, used as TV antenna, the principle is different: it is cross-fed, where adjacent elements are fed in opposite phases.

  KEYCOM's aircraft antennas offer excellent weather resistance and are designed for use in severe conditions.

Customization of this antenna is available upon your request.
