摘要: This communication presents a low-loss hybrid technology for integration of planar circuits with high-efficiency off-chip antennas. A linear antenna array fed by synthesized version insulated image guide operating in E11x mode (where the electric field is primarily parallel to ground-plane) designed and measured. on-chip dipole couples fields efficiently from feed line. Measured coupling insertion loss about 0.5 dB at 90 GHz. broadside gain 14.9 dBi GHz measured an 10 radiating elements.
