This paper shows the comparison in two designs i.e. L shape and u shape of millimeter wave (mm-wave) array antenna. L shape antenna has two identical sub arrays having four patches in each array whereas u shape antenna has three identical sub arrays with four patch on each array arranged along the edges of the mobile phone pcb, both have been designed by neltecny9220 material with dielectric constant (ε r ) 2.2 and loss tangent (tanδ) 0.0009 has an array size of 48x12x0.787 mm3 .proposeddoi:10.22214/ijraset.2017.11111 fatcat:tdycgitpjfgrtgkixum74rmvie
