WebbWe propose a deterministic-statistical method for an inverse source problem using multiple frequency limited aperture far field data. The direct sampling method is used to obtain a disc such that it contains the compact support of the source. The Dirichlet eigenfunctions of the disc are used to expand the source function. Then the inverse problem is recast as … WebbA compact dual broadband dual-polarized shared-aperture antenna array is proposed for base station applications. The shared-aperture antenna array consists of a dipole antenna operating at the lower band (LB) of 0.69-1.52 GHz, and a 2×2 antenna array operating in the higher band (HB) of 2.3-5 GHz. Low-pass partially reflective surfaces are introduced for …
Webb7 nov. 2024 · Abstract: A C-/Ka- band circularly polarized (CP) shared aperture antenna array is proposed. The C-band antenna array is composed of $4\times 4$ cross dipole antenna elements. Notably, each antenna elements are fed by a 1-to-2 power dividers with the output phase difference of 90°, which enables them to generate left/right-hand CP … WebbAnswer (1 of 2): Antenna technology using shared aperture antenna (SAA) for dual band operation or using polarization diversity is of immense use in communication, especially …
