KH30 Series Active Antenna

Product Introduction

•Highly Sensitive Effective Antenna Source:

With the establishment and development of electromagnetic compatibility standards, there is a great need for detecting weak electromagnetic field interference signals in space. The antenna factor (also known as antenna effective height; antenna correction factor; antenna attenuation factor) of passive whip antennas (for electric field measurement) and loop antennas (for magnetic field measurement) attenuates by about 90~50dB in the 0.5KHz frequency range from low to high frequencies. This makes it difficult to detect magnetic fields below 50dB across the entire frequency range even with the best contemporary EMI test receivers. CISPR Publication 16 clearly allows the use of active antennas that comply with CISPR standards. Our developed KH30251(whip antenna series) and KH30253 (loop antenna series) are designed based on this principle.

This series of antennas are broadband type, requiring no tuning across the full spectrum, especially suitable for automatic multi-frequency point measurement scenarios.

Operating frequency range: 9KHz~30MHz (can be extended up to 50MHz and down to 500Hz)

•Broadband Star-shaped Antenna (Passive Type):

With the development of television, communication, and radar technologies, the frequency range has gradually expanded to the meter wave band. There is an urgent need for broadband, high-gain antennas for transmitting and receiving space radio signals, replacing the hassle of requiring different antenna structures for different frequency bands. The antenna can simultaneously transmit radio signals across multiple frequency bands.

•FM signals (30~60MHz,88~108MHz);

•TV signals (60~860MHz);

•Mobile phone signals (470~960MHz);

•Computer antenna internet signals (2.4~3GHz)

For this purpose, we have developed two types of star-shaped broadband antennas and obtained national patents (Patent No.: ZL20102011056816)
