Wide band long slot array antennas

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.
