The availability of receive array coils at high field, small bore animal scanners is limited by the lack of space for classical transmit volume resonators coupled with its inability to generate homogenous transmit B1 field due to wavelength effects. We explore the possibility of the traveling wave concept for spin excitation along with the phased array technique for signal reception at 16.4T. To this effect, a 3-channel phased array coil and a patch antenna were designed and combined. Signal to noise ratio and parallel imaging techniques were studied and achieved SNR equivalent to that of a quadrature surface coil.
