This paper presents a broadband cross-shaped patch antenna with an elliptical slotted ground plan as single unit for coming 5G wireless communication networks. The proposed single antenna has resonating wideband frequencies from 22 to 45 GHz, which cover 28 GHz and 38 GHz operating frequency. The radiation efficiency of the single unit antenna is 92% at 28 GHz and 90% at 38 GHz. The measured return loss of at 28 GHz is -17.66 dB with maximum gain of 3.81dBi while return loss of 38 GHz is -13.24 dB with maximum gain of 4.86dB. The antenna is designed on low loss Rogers’s 5880 substrates with dielectric constant 2.2 and dielectric loss of 0.009. The antenna has compact dimension of 0.392λ0 × 0.392λ0 × 0.019λ0 at 28 GHz. The proposed single unit antenna also fabricates in lab and validate with reflection coefficient simulation results. An 8×8-array configuration is also investigated to achieve maximum gain of 18.3dBi at 28 GHz and 20.7 dBi gain at 38 GHz, respectively. 3D electromagnetic simulator CST microwave studio and HFSS are applied for the layout design and characterizations of the antenna performance..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
