Array Antennas
-
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and superpose, adding together (interfering constructively) to enhance the power radiated in desired directions, and cancelling (interfering destructively) to reduce the power radiated in other directions. Similarly, when used for receiving, the separate radio frequency currents from the individual antennas combine in the receiver with the correct phase relationship to enhance signals received from the desired directions and cancel signals from undesired directions. More sophisticated array antennas may have multiple transmitter or receiver modules, each connected to a separate antenna element or group of elements.

Horn Antennas
-
Horn antennas can be used for emissions and immunity testing. These antennas are constructed using light weight aluminum with a corrosion resistant conductive coating for indoor or outdoor use. Each antenna is individually calibrated. The calibration data and certificate will be shipped with each antenna.The high gain reduces input power requirements to generate high electromagnetic field levels for immunity testing. High gain also increases antenna sensitivity to low level signals.

Active Dual Loop Antenna
KH30936
-
Beijing KeHuan Century EMC Technology Co,.LTD
KH30936 active dual loop antenna is used for adjusting, testing, measuring and other receivers. It has many advantages:1. The antenna coverage frequency is wide: 150KHz ~ 30MHz .2. The field strength value is measured according to the correction coefficient within the effective frequency range, which is convenient to use.3. The antenna power is supplied by the host, which is convenient for outdoor measurement.4. Compared with the single loop antenna, the advantage is to read the maximum value directly, which eliminates the tedious steps of rotating the antenna to find the maximum value and the interference of the human body to the signal.

Biconical Antennas
-
For many years most standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz. However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas began to be accepted. Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems'' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each Biconical antenna will provide reliable, repeatable measurements.
