Millimeter Wave Antenna Design for 5G Applications

This chapter presents millimeter wave broadband monopole antennas, which are suitable for future 5G mobile network applications. The millimeter wave 5G antenna designs must take into consideration the high propagation loss due to atmospheric absorption at millimeter waves. The chapter considers the design procedure based on a single band monopole antenna, which evolves through stepwise enhancements towards the final goal: an antenna that can operate with wide band characteristics. The enhancements consider notch features that were introduced by embedding an L‐shaped slot on the right bottom corner of the radiating patch. To control the created rejected band, a lumped capacitor was positioned on the best location within the L‐shaped slot and by changing its capacitance values; the notched‐band can easily be shifted downwards over a wide and continues frequency range. The chapter discusses the optimization analysis of the antenna parameters with the aid of using a Computer Simulation Technology EM simulator.
