Fig. 35 Measured and simulated radiation patterns of the proposed antenna array at 60 GHz,
a Port H for horizontal polarization, b Port V for vertical polarization

cross-polarization levels are almost 19.1 dB in two principal planes.

For Port V vertical polarization, as Fig. 35 b shows, the simulated and measured
cross-polarization levels are about

− 22.3 and −

− 21.6 and − 19.5 dB in two principal planes,

respectively.

4 LTCC dual-polarized L-probe patch antenna array with the open-ended
SICs structure for 60 GHz wireless communication applications has been designed
and tested. The proposed 60-GHz dual-polarized antenna array has compact size,
wide bandwidth, good isolation, high gain and wide 3-dB gain bandwidth by em-
ployed the multilayer SL feeding network, “differential feed” L-probe approach, and
open-ended SICs.
