Abstract: The characteristics of a planar 8 $\times$ 8 array of a 3-mm waveband receiver antenna elements loaded with low-barrier planar Mott diodes have been studied. Experimental data on the radiation-directivity patterns (RP) and sensitivity of antenna elements in the two-dimensional array are presented. The average RP width for central elements amounts to $\sim$35$^\circ$ in the $E$ plane and $\sim$50$^\circ$ in the $H$ plane. In the operating frequency range (90–100 GHz) of the matrix receiver, the average voltage responsivity is on the order of 9000 V/W at a noise equivalent power of about 5 $\times$ 10$^{-12}$W $\cdot$ Hz$^{-1/2}$.
