چکیده
This work presents the design, fabrication, and measured results of a fully integrated miniature rectenna using novel tunnel diode known as Asymmetrical Spacer Layer Tunnel (ASPAT). The term is an abbreviation for rectifying antenna, device with rectifier antenna coexisting single design. ASPAT centrepiece used its strong temperature independence, zero bias, high dynamic range. designed to be impedance matched rectifier, eliminating need matching network saving valuable real estate on gallium arsenide (GaAs) substrate. chip, thus enabling miniaturisation due dielectric constant GaAs spiral enables design fabricated economically substrate whilst being comparable in size 15-gauge needle, unlocking applications medical implants. presented here has total die 4 × 1.2 mm2, maximum output voltage 0.97 V 20 dBm single-tone 2.35 GHz signal transmitted 5 cm away from rectenna.

We demonstrate a new thin-film graphene diode called a geometric diode that relies on geometric asymmetry to provide rectification at 28 THz. The geometric diode is coupled to an optical antenna to form a rectenna that rectifies incoming radiation. This is the first reported graphene-based antenna-coupled diode working at 28 THz, and potentially at optical frequencies. The planar structure of t...

Compound semiconductor devices are commonly used in today’s wideband communications systems. In particular, they are indispensable to build the front-end stage, which is required to process high-frequency signals. Introduction of resonant-tunneling diodes (RTDs) to the front end would result in even better system performance. In the long term, such efforts are expected to pave the way for post-...
