“…However, diodes are not suitable for identification and wireless power transmission applications due to their low dc-to-RF efficiency [15], [16]. On the other hand, transistors such as HEMT have high dc-to-RF efficiency, low heat dissipation, and low noise figure, which are critical factors in identification and wireless power transmission applications [15], [16].…”

This paper demonstrates the design of an 800-MHz solar-powered active wireless beacon composed of an antenna and an integrated oscillator on a low-cost paper substrate. Inkjet printing is used to fabricate the conductive circuit traces and the folded slot antenna, while the oscillator circuit is designed using off-the-shelf components mounted on the paper substrate. Flexible, low-cost, amorphous silicon (a-Si) solar cells are placed on top of the slot ground and provide autonomous operation of the active circuit eliminating the use of a battery. A prototype is built and characterized in terms of phase noise, radiation patterns, and the effect of solar irradiance. Such low-cost flexible circuits can find significant applications as beacon generator circuits for real-time identification and position purposes, wearable biomonitoring as well as solar-to-wireless power transfer topologies. The measured phase noise is 116 dBc Hz at 1-MHz offset, while drain current is 4 mA and supply voltage is 1.8 V.

This paper describes a design method in the millimeter‐wave frequency region for an aperture‐coupled microstrip antenna which unifies a feed network consisting of a monolithic microwave integrated circuit (MMIC) which affects the antenna characteristics at millimeter‐wave frequencies, the shift of the location of the radiating element which is important in actual configuration in the millimeter‐wave region, and the effect of the adhesives. Based on this design, an antenna was fabricated. A quartz substrate was used for the radiating element, while a GaAs substrate was used for the feed network. A high radiating efficiency of 87.1 percent and a wideband characteristic of 3.1 percent with VSWR < 2 were attained. As an application of this structure, a test fabrication is reported on the aperture coupled microstrip antenna in the 40‐GHz band in which an MMIC frequency converter is integrated.
