Reviewer 2 Report

In this paper, authors have proposed the broadbeam microstrip patch antenna using parasitic patches and slot-coupling. The simulated and measured results are presented. Authors are suggested to incorporate the following:

1. The paper focusses on broad beam patterns. The normalized patterns should be incorporated instead of absolute patterns, so that 3 dB beamwidth can be observed.
2. The analysis of single element and 5X5 array is given. What about 2X2 and 3X3 arrays?
3. In the abstract, please correct ‘computer science technology software (CST)’ as ‘Computer Science Technology (CST) microwave studio’.
4. The max. gain and bandwidth should be mentioned in the abstract.
5. In Fig. 2, simulated results are given, however, the image of fabricated antenna is inserted in the figure, it should be removed.
6. The quality of some figures should be improved, especially Fig. 2, Fig. 12, Fi. 13, Fig. 16 should be improved.
7. The antenna operates for sub-6 GHz 5G communications, some recent papers of sub-6 GHz 5G antennas should be included in the paper.

Reviewer 3 Report

The quality of some figures should be improved.

In Fig.1, Cx should be replaced by Cz.

The parameters analysis for the single patch antenna should be performed and compared with the patch antenna with parasitic patches to better demonstrate the efficacy of the proposed antennas.

Round 2

Reviewer 2 Report

Authors have addressed almost all the comments. The radiation patterns provided by the authors in Fig 16 are not normalized as the peak is going beyond 0 dB. Authors are suggested to convert the data of these graphs into absolute values and divide these values by the maximum value to obtain the normalized data. After that convert this data into dB and plot it. All graphs for normalized patterns should touch 0 dB for both simulations and measurements.
