Modern wireless communication systems require high bandwidth to meet with the recent 5G technology requirements. With an increasing number of devices, sensors, and IoT systems, an exponential growth of the technology is bound to happen. 5G technology opens a new millimeter wave spectrum, and efficient antennas are needed to achieve low losses to accommodate huge amount of data flow. This paper discusses a series feed antenna and out-of-line series feed antenna at 26 GHz. An optimized eight element structures for both antennas with high gain and wide bandwidth performance. Initial results shows that the series feed antennas yield 45% bandwidth wider, and the out-of-line series feed antennas increased the gain from 12.3dB to 16.1dB.
