Abstract :
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.
