In this paper, an electromagnetic diode with TEM mode, such as MILO, is connected directly to a Dual Mirrored Slotted Array Antenna (DMSAA). To convert a donut-shaped pattern of the electromagnetic source into a directive pattern, mode converters have been used in the past. But their losses, weight, size, and cost additions impact negatively on total system performance. Due to not using any mode converters, this is useful. Given the input is an electromagnetic diode with a TEM output mode, a large bandwidth is unnecessary. Therefore, slot antennas are used. Usually, array antennas were commonly used to increase the directivity and beamforming at the output of mode converters. To convert a donate-shaped pattern into a directive, half of the aperture fields must be rotated 180°. Here, the diode outlet is connected to the DMSAA with an inherent phase difference of 180° of the electric fields. For this purpose, a power divider and a pair of narrow wall slotted array antennas (NWSAA) have been used. The antenna is simulated at 10GHz frequency. The results show a fully directive beam with a side lobe level (SLL) below -10dB. Also, S11 is -16.5dB, at 10GHz frequency. Because the mode converter is completely removed, this structure is very suitable for compact applications.
