Highly Integrated Ligthweight Dual Band Antenna with Dual or Quadruple Polarization Agility

Wireless and mobile communication often calls for dual-band antenna modules. Presently, agility in polarization properties in such antennas is getting on a sense of urgency. The antennas desired by the industry should be manufactured in the lightweight technology supporting high degree of integration between antenna elements and microwave feeding circuits. The well suited approach is use of multilayer composite panels carrying at the bottom side microwave printed circuits needed to generate at least two polarizations. This paper presents the results of our research on dual-band antenna modules with an integrated compact microwave feeding network.
