Dear all,
I need to design a Vivaldi antenna working at 61GHz. The directivity should be more than 10dBi (59-63GHz). This antenna is feeded by differetial signals (used microstrip to slotline transition) and both of the two slotlines are fabricated on the same side of the substrate.
Right now the first sidelobes in the H-plane is too high (only 5dB below the mainlobe). Is there anyone knows how to improve the H-plane pattern? Or which parameter is essential to the H-plane pattern. Thanks a lot.
