Microstrip patch array antenna
A microstrip array with mutual coupled rectangular patch radiators is described. By the avoidance of a corporate feeding network, advantages in the antenna performance and design are realisable. Experimental results are presented for both linearly and circularly polarised antennas which demonstrate the usefulness of this special antenna configuration.

Ultra‐High Isolation Decoupling and Matching Network for mmWave Antennas in Near‐Range FMCW Radars
ABSTRACT A decoupling and matching network (DMN) based on substrate integrated coaxial line technique is proposed to suppress the mutual coupling between a pair of transmitting and receiving antennas operating at 35 GHz. The distorted radiation patterns, typically observed in closely spaced antennas, were improved by introducing carefully designed ...

Our 8‐Tx/32‐Rx coil is based on two rows of transceiver microstrips intertwined with receive‐only loops. Comparison of the intrinsic SNR at 7 and 11.7 T leads to a 2.2 ratio for the human brain, and 2.75 for a 16‐cm agar sphere, translating into α = 1.5 and 1.95 in the B0α$$ {B}_0^{\alpha } $$‐SNR model, respectively.
