Effective Solutions

Drug research and development is a complicated, time-consuming, and costly process. There exists no single way through which drug discovery takes place. Each team taking part in drug discovery has its own strengths and weaknesses.

To increase strengths and reduce weaknesses, everyone must improve their ability to extract added value from the already available information. The amount of proteins that may become pharmacological targets exceeded several thousand; taking into account the alternative splicing, posttranslational modifications and protein-protein interactions this number increased to several millions; number of already synthesized small organic molecules that may be used as ligands inhibiting or stimulating those targets is more than sixty millions; the number of virtual molecules generated in computer surpassed hundred billions.

Effective utilization of this information requires application of computational methods, which allow selection of targets and their ligands most promising for treatment of certain disease.

Working in this field for more than twenty years, we developed and validated a few predictive tools that currently available as separate web resources. Our long-term goal is not just improve and extend these tools but integrate their functionality providing better services for particular needs of researchers working in the field of drug discovery.

The log-periodic antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
In terms of its specification, a typical log periodic antenna might provide between 3 and 6 dB gain over dipole for a bandwidth of 2:1 while retaining a VSWR level of better than 1.3:1. With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.

EMC/EMI pre-compliance test antenna.
Very high gain over the full frequency range.
 Meets latest EMC standards up to 7GHz.
Suitable even for immunity measurements
