At the C‐band, a double‐layer series‐fed linear array antenna is proposed. T‐shape and interdigital microstrip transmission lines are used to increase the impedance bandwidth and obtain a reduced sidelobe level (SLL). The antenna has a bandwidth (BW) of 28% (VSWR ≤ 2), a SLL of −20 dB and a gain of 13.5 dB across the BW of 23%. Details of the antenna design and the experimental results are presented.
