A parasitic superdirective electrically small coil array based on printed loop antenna for magnetic resonance imaging (MRI) applications is presented. The proposed coil array is composed of two coils wherein one of the coils is excited and the other is loaded with a tuning capacitor acting as a director to generate directional near-field distribution. The coils are with identical diameter of 30 mm...
A phased array system simulator to design and optimize complete active phased array front-ends, including the radiation pattern, is presented. It can simulate the radiation pattern in the circuit simulator with the incorporation of the nonideal effects in the circuits and mutual coupling between elements in the antenna array. The effects of any imperfection of practical circuits on the radiation pattern...
A tunable decoupling and matching network (DMN) for a two-element closely spaced antenna array is presented. The DMN achieves perfect matching for the eigenmodes of the array and thus simultaneously isolates and matches the system ports while keeping the circuit small. Arrays of closely spaced wire and microstrip monopole pairs are used to demonstrate the proposed DMN. It is found that monopoles with...
Beam steering with high front-to-back ratio and high directivity on a small platform is presented. Two closely spaced antenna pairs with eigenmode port decoupling are used as the basic radiating elements. Two orthogonal radiation patterns are obtained for each antenna pair. High front-to-back ratio and high directivity are achieved by combining the two orthogonal radiation patterns. With an infinite...
