A Compact Circular Rectenna for RF-Energy Harvesting at ISM Band

Round 1

Reviewer 1 Report

The article presents significant shortcomings both in the implementation methodology and in the state of the art of the subject. There is no comparison with other similar works and the references in the state of the art are few and poor. Has the proposed rectenna finally been implemented? If so, where is the comparison between simulation and experimental results? Please implement the required additional experiments for a comprehensive presentation of this work and expand the introduction of the article by including the following study in the citations:

Reviewer 2 Report

The paper presents a rectenna designed for the ISM band. It consists of a circular monopole antenna, a doubling rectifier stage, and a matched filter between the two. The paper is quite well written and presents the approach well. However, the paper does not really present any originality because each of the elements taken separately (antenna, matched filter, or rectifier stage) are well known structures. Taken as a whole, this type of rectenna has already been published many times. It is therefore not interesting to publish a work based on simulations. Only a realization with tests in a real environment would be interesting for publication. On the other hand the antenna described in the paper "Dual band Wearable Antenna for ISM band Application 1Aysha Safeena A.M, 2Dr.S.Perumal Sankar, 3 Sreelekshmi published in "February 2017 IJSDR | Volume 2, Issue 2" has very similar characteristics to the proposed paper and is not in reference. Moreover, the antenna by the authors also has another potential operating frequency around 4.2GHz and is not exploited.
