4. Low-dispersive Leaky-wave Antennas: A Viable Approach for Fifth Generation (5G) mmWave Base Station Antennas
University essay from KTH/Elektroteknisk teori och konstruktionAbstract : In this work, a method to achieve reduced beam-squint in fully metallic leaky-wave antennas is proposed and its applicability for high frequency, high gain, base station antennas in future communication networks is indicated. The antenna is built in gap waveguide technology, where the fundamental mode is allowed to leak by removal of one of the waveguide walls. READ MORE

5. Helical Waveguides With Higher Symmetries
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Helical waveguides are widely used today as slow wave structures and as normal or axial mode antennas. By introducing higher symmetries in the structure the dispersive properties of the waveguide can be manipulated and the helices can be made to radiate energy as leaky wave antennas. READ MORE
