A grid array antenna is a radiation element of linear polarization. The feed point is located at the left or right edge of the antenna structure. As the frequency changes, the beam direction varies due to the phase change in the current along the grid cells. This paper presents the radiation characteristics when the grid array antenna is excited from its center point. For this excitation a coaxial line is used. The frequency response of the gain in the broadside direction is evaluated. Special attention is paid to antenna dimension reduction. The antenna dimensions can be reduced by shortening the side length of each grid cell. A comparison between the gains of the grid array antennas with and without dimension reduction is made and discussed.
