This paper proposes an ultra-wideband frequency-invariant beamforming (FIB) using a generalized nesting array. To implement ultra-wideband (9:1 bandwidth ratio) FIB with a reduced number of array elements, the target frequency band is divided into su

This paper proposes an optically transparent series-fed microstrip array with small inter-element spacing and stepped feed lines for antenna-on-display applications. In the proposed series-fed array, the inconsistency of resonant frequencies between

This paper proposes four methods and empirical formulas of adjusting characteristic impedances for thin-metal mesh transmission lines. The characteristic impedances are discretely adjusted by changing the number and the size of unit meshes, which pro

This paper proposes a pattern distortion coefficient as a new figure of merit to quantitatively evaluate both mutual coupling and pattern distortions in multi-antenna systems. The proposed coefficient is defined as a cross correlation between unaffec
