This paper presents a novel wideband high gain rectenna (rectifying antenna) for RF energy harvesting. The proposed device consists of a double-sided antenna, a low-pass filter and a doubling rectifying circuit using Shottcky diodes as rectifying elements. It works over the frequency range from 1.9 to 3.2 GHz. The simulated results demonstrate that the maximum rectenna conversion efficiency is nearly...
To fulfill co-located dual-polarized directional radiation, a dual-port patch antenna is presented. Constructed on a microwave PCB, the patch element is a foursquare of two open slots. The designed antenna can radiate the patch antenna mode while fed by the coaxial line (port 1), and the folded dipole mode while fed by the coplanar stripe (port 2). The experimental results show that the operating...
A dual-polarized ceiling-mounted antenna, based on previous ceiling-mounted antennas is proposed in this letter. It consists of one vertical polarization unit and one horizontal polarization unit. The vertical polarization unit is a transformation of a monopole, looking like a tundish. And the horizontal polarization unit comprises of four dipoles on a substrate ring. The two units compose a nesting...
In order to build Timely and effective communication in HF blind-spot (20-100KM), Cobwebb folded dipole antenna was designed as well as matching circuitry. In this paper, antenna structure and antenna electric-height are simulated and amended in the use of electromagnetic simulation software FEKO. Antenna radiation patterns in the different electric-height are given. It is clear that the proper electrical...
