So far, most travelling wave studies have used a patch antenna to create the travelling wave, as they are simple in design and can be constructed rapidly at little cost. In this study, both a patch antenna and an end-fire helix antenna are simulated and constructed to allow their relative merits to be assessed. Simulations are used to asses specific absorption rates (SAR) and experimental data are used to assess the signal to noise ratio (SNR) and B1 homogeneity of both antennas.
