In this study, a compact multiband, low-profile and low-cost microstrip antenna design covering DCS (Digital Cellular System, 1.7–1.8 GHz), mid-band 5G and Ku-band has been realized. The proposed monopole antenna consists of an elliptical patch element and mushroom-shaped metallic loadings placed on both sides of this patch. The elliptical patch element operates in the 3.3–3.8 GHz range for the mid-band 5G frequency band alone. In addition, the mushroom-shaped structures used on the front surface of the design enables the antenna to operate in the frequency ranges of 1.72–1.8 GHz DCS and 10–15 GHz Ku-band, as well as the 5G operating frequency. The proposed microstrip line fed antenna is 50 × 40 mm2 in size. The antenna has a bandwidth of 1.71 GHz and a maximum gain of 5.73 dBi at the 5G operating frequency. In addition, the designed antenna has a bandwidth of 80 MHz for the DCS band and 5 GHz for the Ku-band. The simulations of the proposed antenna were carried out in the CST Microwave Studio and the obtained performance parameters are presented in detail. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
