Scanning transmit antennas can be used in wireless power transmission systems in order to optimize the power budget and energy consumption in the far-field. Here we present a concept for beam scanning that minimizes the need for reconfigurable RF components, such as diodes or varactors, and therefore reduces cost and power handling considerations. Instead the beam steering relies on a frequency scanning principle. In this paper we present the basic theory for designing such a frequency scanning antenna and by means of an example, that conforms with 2.45 GHz ISM band requirements, we evaluate its performance. Analytical and numerical simulations are presented.

Abstract

Scanning transmit antennas can be used in wireless power transmission systems in order to optimize the power budget and energy consumption in the far-field. Here we present a concept for beam scanning that minimizes the need for reconfigurable RF components, such as diodes or varactors, and therefore reduces cost and power handling considerations. Instead the beam steering relies on a frequency scanning principle. In this paper we present the basic theory for designing such a frequency scanning antenna and by means of an example, that conforms with 2.45 GHz ISM band requirements, we evaluate its performance. Analytical and numerical simulations are presented.
