    Title: Efficient Array Antenna Design for mmWave Applications

    Abstract:
    Recently, interest in millimeter wave antennas has increased due to the high demand for faster data and reliable service in mobile communication. One of the driving forces is the fifth generation (5G) of the wireless network, which aims to provide such requirements. To handle such a demand, the systems should utilize the millimeter-wave bands. Path and material losses increase as frequency increases, reducing system efficiency. Therefore, there is a need for efficient millimeter-wave guiding structures that overcome such limitations. Gap waveguide technology is found to overcome such limitations at millimeter-wave bands. The advantages of this structure are in its suitability for millimeter wave applications as it is self-packaged with no radiation losses. Such a guiding structure has around 1:2 bandwidth that can also be enhanced under some conditions.

    In this talk, several highly efficient antenna arrays will be presented based on the use of the gap waveguide technology. In addition, examples of added functions to the arrays will be presented, such as diplexers separating transmit and receive bands and monopulse arrays with compact comparables based on gap waveguide technology and leaky wave antenna arrays for frequency scanning properties.
