The deployment of Ka-band radar necessitates addressing increased losses due to rain and free-space propagation, in addition to achieving low sidelobe levels (SLL). Substrate integrated waveguide (SIW) slot antennas, with their high-power handling ca

In this work, we present a compact four-direction beamforming 5G antenna based on a stacked $4\times4$ Butler matrix and a microstrip patch array antenna. The proposed beamforming antenna is a stacked-up structure using the low temperature co-fired c

This paper introduces a miniaturized Butler matrix design method using a folded structure. The Butler matrix was fabricated in multi-layers using low-temperature co-fired ceramics (LTCC) and designed to operate at 28 GHz. The conventional one-plane B

This paper proposes a tapered slot antenna with band-stop characteristic at Ka-band. In order to create a 28 GHz stopband and reduce sidelobes, SRRs are added on the feedline and corrugations are formed on both sides of the antenna. Through these str
