Beam-scanning SIW antennas based on association of various shaped slots | IEEE Conference Publication | IEEE Xplore
This paper presents a new switched beam antenna array working at 26GHz for future 5G application, based on the sub-arrays containing an association of various shaped slot (L, U, S) engraved in Substrate Integrated Waveguide (SIW). The phase shift between each slot is obtained by adjusting the position of transversal slots. The beam tilt is obtained by choosing the adequate slots combination. Finally SPDT switches can be used to control the antenna beam in 8 different directions between -46° and 46° in the same plane or to combine different sub-arrays to carry out multi-beams antenna array. Results of simulations (CST Microwave) are given and validate the proposed solution.
