This application is related to slot-array antennas, in particular, to wide-bandwidth long-slot antenna arrays. Slot-array antennas have apertures theoretically capable of maintaining a constant driving impedance of 377 ohms (Ω) over a wide-bandwidth, for example, over a bandwidth greater than F max −0.01*F max (i.e., 100:1). However, conventional long-slot antenna arrays are limited by Wide-Band Slot Antenna Arrays With Single-Layer Corporate The paper describes two test antennas: a 4 × 1 linear slot array and a 2 × 2 planar slot array. Both have been fabricated and tested at Ku- band. The linear array shows more than 20% bandwidth and the 2 × 2 array shows a bandwidth of 21% for 10-dB return loss. There are good agreements between measured and simulated patterns for both antennas.

Abstract—In this paper, the design of slots array antennas based on Substrate Integrated waveguide (SIW) has been analyzed and simulated. A waveguide slot antenna has a vertical row of slots along the length of a vertical waveguide, with the array of slots increasing the gain by flattening the vertical beam.
