Single frequency network (SFN) has been widely used in digital terrestrial television broadcasting (DTTB) systems. In this paper, we propose a SFN structure for DTMB systems using satellite links as the main program distribution networks. The proposed structure is more suitable for constructing national wide or large area DTTB SFN under complicated environments. The network structure and key technologies...
This paper presents a 60GHz planar on-chip antenna fabricated with a standard 0.18-μm CMOS process. The antenna has a U-shaped radiating patch, which is fed by a 50-Ω coplanar waveguide (CPW). It has a compact size of 1.5mm × 1.5mm × 0.26mm. The simulation work is optimized by using an FEM-based 3-D commercial EM software Ansoft HFSS. Simulated results shows that the on-chip antenna has a good impedance...
This paper presents a 45GHz on-chip antenna for Q-LINKPAN applications. The antenna has a simple triangle radiating patch that is fed by a 50-Ω modified coplanar waveguide (CPW) structure. Implemented results denote this antenna has a favorable impedance bandwidth from 40–50 GHz, where nearly omni-directional radiation patterns and stable gain are also obtained and shown. Besides, it has a very compact...
