In this paper, a rectangular microstrip patch antenna was designed for 5G high speed data transmission in the Millimeter-Wave (mm-wave) range from 75 to 110 GHz (W-band). The proposed design is a single element microstrip antenna that has an overall size of $2.02 \times 2.328\times 0.149\mathrm{mm}^{3}$. The radiating element having a dimension of $1.1483\times 1.429\mathrm{mm}^{2}$ is printed on a substrate material (RT/Duroid5880) with a height of 0.149 mm. Inset feed technique is used for matching between the feeding microstrip line and the rectangular radiating patch. The antenna provides a fractional bandwidth of 3.76% (about 3.12 GHz) and covers the range from 81.3717 GHz to 84.4912 GHz centered at 83 GHz. Further, the return loss, VSWR, gain and directivity achieved are 55.7937 dB, 1.0033, 7.9087 dBi and 7.8914 dB respectively. Good impedance matching, bandwidth, radiation characteristics at the operating band along with compact and small size confirm that the proposed antenna is suitable for 5G mm-wave applications. |
