Recently the use of traveling waves for high field MRI has been suggested as a promising method for large FOV imaging and comparatively uniform excitation. In the traveling wave system, conventional volume coils and surface coils used as the transmitter/receiver are replaced by a patch antenna, a kind of directional electromagnetic antenna, placed a considerable distance from the sample. Here, we provide details of our experience in the practical design of a patch antenna, and document its properties for traveling wave generation in a 7 Tesla scanner bore.
