Studies from University Erlangen-Nurnberg Provide New Data on Microwave and Wireless Technologies (Size-reduction and suppression of cavity-resonances in hybrid mm-wave antennas for polarimetric measurements)

By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Microwave and Wireless Technologies have been presented. According to news reporting originating from Erlangen, Germany, by VerticalNews correspondents, research stated, "Size and feed structure are some of the important constraints for using antenna-elements in multi-element two-dimensional arrays, where easy planar integration and appropriate matching with transceiver chips are essential. This applies especially when differential signaling and adaptable polarization are required."

Our news editors obtained a quote from the research from University Erlangen-Nurnberg, "Based on a balanced-fed patch-excited cavity-backed horn antenna (hybrid antenna), feeding concepts, and approaches to reduce size are discussed and evaluated in this paper. The influence of the substrate-integrated cavity is analyzed and methods to overcome the restrictions are presented, together with simulated and measured results. The antenna elements are evaluated with regard to their use in multistatic and polarimetric sparse arrays, which will be briefly introduced."

According to the news editors, the research concluded: "The optimized antennas achieve 10dB return loss, a gain of more than 5 dBi as well as symmetric and homogeneous radiation patterns in amplitude and phase with low cross-polarization in the desired frequency-band of operation between 70 and 80GHz."
