Traveling-wave excitation in ultra-high field MRI has been introduced in an effort to increase field of view and to enhance RF transmit field homogeneity. Here we present initial results at 300 MHz using a recently-developed patch antenna for excitation. The antenna is 80% smaller in size than conventional patch antenna and has an asymmetric design to produce a circularly-polarized field with only a single feed.
