Abstract

We propose and demonstrate a 2 ?? 4 T-type folded substrate integrated waveguide (TFSIW) slot array antenna. Each linear array is fed through a microstrip line and a TFSIW Y-junction. The size of the proposed antenna is reduced by 40% and the impedance bandwidth (-10 dB) is 5.6%. The dimensions of the structure are presented and the proposed array antenna is fabricated in a two-layer substrate. Simulation and measurement of the proposed antenna are compared.
