As a significant part of the wireless communication system, the antennas are required to achieve broader and broader bandwidth to meet the rapid development and innovation challenges in the emerging applications such as 5G mm-Wave communication. A traditional method is to adopt multi-layer structures, such as air cavity-backed, substrate integrated waveguide and metasurface. 

 

To further enhance the bandwidth and gain of patch antenna under low profile condition, the Authors present a Ka-band CPW-Slot-Couple fed patch antenna with single-layer structure for the 5G mm-Wave application. The antenna has a thickness of 0.508mm. The characteristic mode analysis is used to release the mechanism of the enhancement of band with form characteristic mode point of view.

 

The structure of the manuscript is considered and clear. In the introduction, the background and review of the problem's literature were presented on the basis of only 6 publications. The Authors present antenna configuration and parametric study and characteristic mode analysis (CMA). In Simulation and Measured Ressults section, the proposed antenna has been simulated, fabricated and measured to verify the predicted performance: impedance bandwidth and radiation gain, radiation patterns are presented, comparised and discussed.

 

1. Following suggestions should be taken into consideration (they are marked in the manuscript):

Line 14: stars should be replaced by dots - stars are used for convolution

Line 40: is dBic is correct (maybe should be dBi)? 

Line 61: in Fig.1 (not in the Fig.1)

Line 160-190: is better to write f2 and f3 as subscripts

Line 183: please check, if War:Wan should be written using colon or /

Line 206: is @ correct?

Line 236: as line 14

Table 2, right column: as above

Line 253: there is not Patents section

 

2. References should be adjusted to instruction for Authors.

3.References must be numbered in order of appearance in the text - the introduction includes 6 publications (up to line56), next are [24,25] (line 124) and [26] (line 132), [7-10], [11], [16], [21], [13,18] (lines 227-229). There are not [12,14,15,17,19-23]
