Abstract :
A new 50 /spl Omega/ planar antenna structure is presented for finite thickness dielectric substrates. Direct integration of these antennas and commercial MMIC amplifier chips is explored for quasi-optical power combining. A prototype 4/spl times/4 array demonstrated 10 dB gain with 4% bandwidth @ 11 GHz with no matching networks.<>
