The microstrip transmission line has been a popular coil element of choice in multi-element transceiver arrays due to its’ bi-directional current path. An important consideration in microstrip design is the ability to control the transmit field propagation in the transaxial plane. Here in this work, ground plane sidewalls are designed and incorporated as part of the microstrip coil element. Introducing ground sidewalls between microstrip elements can reduce decoupling with neighboring elements, can contain the transmit field near the source, and provide a more efficient coil element.
