[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Dual-port dual-band (28/38 GHz) SIW leaky wave antenna for 5G base stations
摘要： This paper presents a novel dual-port dual-band (28/38GHz) substrate integrated waveguide (SIW) antenna with stepped long slots (SLS) for base stations in fifth generation (5G) communication systems. A stepped long slot on the top side of an SIW waveguide with a changing width creates a wide and rotated beam, which is desired in some specific 5G applications. One of the unique advantages of the design is its embedded duplexer separating the 28 GHz and 38 GHz ports at opposite sides of the antenna. A wide impedance bandwidth in both bands is obtained. The realized gain of the antenna is around 11.56 dBi and 12.08 dBi in both bands, respectively. The 6 dB beamwidths are 23o and 16o at 28 GHz and 38 GHz. The structure has good frequency scanning properties and is suitable for sectored base station topologies.

摘要： The determination of the focal length in lens antennas is usually difficult. This work applies the potential of a code used for the implementation of a full-wave, two-dimensional (2D) electromagnetic simulator based on the method of moments (MoM), which allows solving in very short time electromagnetic scattering problems using the two-dimensional (2D) Lippmann-Schwinger equation [1-3]. The results obtained with this code of hyperbolic lenses and biconvex lenses allow determining the location of the focus and comparing them with theoretical analytical results.
