“…This study examines the optimization of the traveling wave approach by empiric analysis of the coupling position to achieve good field homogeneity and efficiency. Additionally, a novel concept of multimode excitation is demonstrated by employing a dedicated three‐port antenna (10). The performance of multimode excitation is analyzed thoroughly by simulations and phantom measurements.…”

Given the absence of a body coil, the radio frequency screen of a whole-body 9.4T magnetic resonance imaging scanner can be used as a circular waveguide. In the unloaded case, the screen allows propagation of the dominant TE11- as well as the TM01-mode. In the first part of this study, the optimum coupling of a circular polarized TE11-mode was determined empirically for excitation and reception with a rectangular patch antenna. Employing full-wave simulations, two simulation models and two phantoms, different patch positions were tested to find the optimum position with respect to coupled power and homogenous excitation field. The best simulation results were validated with measurements. The second part of this study describes the design and measurements of a multimode excitation device. Using the parallel transmit system of the MR scanner, all propagable traveling wave modes could be excited and detected independently. The performance of the multimode device related to field of view, B1+-efficiency and radio frequency shimming was assessed by phantom measurements. Initial results show that three modes are sufficient to homogeneously excite regions of interest at 9.4 T.

This paper presents a multiband compact microstrip MIMO antenna for Unmanned Air Vehicle, GPS and WLAN applications. It consists of two symmetric triangular spiral shape patch and defected ground structure (DGS). The antenna is designed using low cost FR4 Substrate and analysed by using commercially available electromagnetic simulation software CST. The simulation results shows the designed antenna has resonance frequencies at 1.62 GHz and bandwidth from1.6027 GHz to 1.6391 GHz, at 2.42 GHz from 2.3609 GHz to 2.4667 GHz and 3.79 GHz from 3.6418 GHz to 3.7909 GHz frequency which covers GPS, WLAN and UAV(LTE band) applications respectively. Detailed physical analysis of proposed antenna is presented and the characteristics of antenna are verified by the return loss, insertion loss, gain and directivity. It is found that it has good performance for above applications. The overall size of the antenna is 28 x 20.5 mm2 which is less than the conventional antenna by 84% at lowest resonating frequency of 1.62 GHz.
