Design and analysis of millimeter wave series fed microstrip patch array for next generation wireless communication systems

Abstract

A Millimeter-wave series-fed microstrip patch array antenna that operates over the band 27.6 GHz to 30 GHz is presented in this paper. The designed antenna shows a reflection coefficient less than -10 dB over the proposed band. The antenna has a fan beam radiation pattern with 3 dB beamwidth of 9 degrees in the E-plane and 66 degrees in the H-plane. The calculated gain of the proposed antenna is 15.4 dBi. The pulse dispersion effect is quantified by calculating the pulse fidelity factor (PFF) of a transmitted pulse having 500 MHz bandwidth with a center frequency of 28 GHz. The designed antenna exhibits more than 0.9 fidelity factor value, which makes it suitable for wireless data communication systems.
