5.8GHZ Rogers 5880 PCB HF Printed Circuit Board Sensor Module Application
A directional PCB antenna was required to operate in the 5.725 ‐ 5.850 GHz ISM band with linearly polarized waves. The antenna had to interface with a 50 SMA connectorization and be fabricated entirely from circuit traces, metal components, and solder. No discrete electrical components could be used.
Additionally, the entire device had to fit within a 10 cm x 10 cm x 1 cm rectangular prism.

Description:
A dielectric material is a substance that is a poor conductor of electricity, and used as an insulating layer in the PCB build up. Porcelain, mica, glass, plastics and some metal oxides are good dielectrics. The lower the dielectric loss, (the proportion of energy lost as heat) the more effective the dielectric material. If the voltage across a dielectric material becomes too great -- that is, if the electrostatic field becomes too intense -- the material will suddenly begin to conduct current. This phenomenon is called dielectric breakdown.
Our high density circuit boards have the technology pushing capabilities to drive applications in a large number of industries including but not limited to semiconductor test equipment, defense, medical and aerospace.
