Millimeter wave frequency scanning antenna for body centric communication

Millimeter wave spectrum is the main candidate for body centric wireless applications such as health monitoring, live streaming, and gaming. In this paper, a frequency scanning microstrip antenna array is designed as it provides reconfigurability in the direction of main beam pattern. The designed antenna is an array of 16 elements with the measured impedance bandwidth from 33GHz to 40GHz. The S₁₁ is better than -10 dB and S₂₁ of less than -10 dB is achieved. The beam shift is obtained for frequencies from 33GHz to 36GHz with shifts from -45° to -31.2° and +31.2° to +45°.
