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.

The multifunctional antennas are designed to meet the harsh environmental conditions and limited space availability found on submarines. This is achieved by utilizing a unique stack array enclosed within a protecting fibre glass dome.The antenna characteristics has been developed in such a way so that aircrafts can also operate in the airspace for data and voice communications next to ship-to-ship or ship-to-shore communications. In this way aircrafts e.g. AWACS act as relay stations to transfer radio signals. Although the dipole of the lizard has a primarily plane oriented radiation characteristic – up until an elevation angle of 60 degrees-, submarines can still track aircrafts up to an elevation angle of 90 degree. This guarantees complete coverage of the surrounding airspace in 360 degree horizontal level as well as in 180 degree vertical level.With this outstanding multifunction antenna capability Aeromaritime significantly extends the military communications for submarines by offering this unique capability.

Biconic Logarithmic Periodic Antennas
Stacked LPDA
-
The stacked Logarithmic Periodic Dipole Antenna consists of two ordinary Log.-Per. structures. The excellent characteristics (flat gain over a large bandwidth, low SWR) of the ordinary Log.-Per. designs could be maintained using the stacked LP design. The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of ca. 2-3 dB compared to an ordinary LPDA. This is especially important for immunity testing, where a maximum fieldstrength and a good field uniformity is required. The beamwidth in the E-plane and the H-plane are nearly identical, providing an optimised illumination of the EuT with minimised ground reflection influence. Further the STLP 9128 C has an excellent cross-polar rejection.
