Abstract

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. 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. The optimized antennas achieve 10 dB 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 80 GHz.
