Abstract

This paper presents the single element dual band switched beam textile antenna. The antenna can operate at frequencies of 0.7 and 2.6 GHz using for 5G wireless communication applications. Textile fabric is considered to be used for substrate layer at the parts of a microstrip antenna for wireless body area network. The beam pattern of antenna can be switched into two directions by changing the position of shorted-circuit points at each edge of antenna. The main beam direction is 45°/225° when corner A is shorted while it steers at 135°/315° when corner B is shorted circuit. The advantage of the proposed antenna is the decrease of the problems like interference, light weight, flexibility and ability to switch beam easily. In addition, the results of the fabricated antenna are compared with the simulated ones. Moreover, the antenna is bent with curvature radius of 6 mm in forward direction. The effects of the bent antenna are studied. The results can confirm that radiation patterns of the bending antenna can be pointed into two directions when changing the positions of shorted circuit. Therefore, the proposed antenna can switch beam patterns, it is flexible, and it can operate at dual-band frequency on textile.
