A linear endfire wideband series fed double-dipole antenna array with low sidelobe level, SLL, and high front to back ratio, F/B, is proposed. The array can provide -27dB SLL at centre frequency of 16.26GHz, 20dB SLL bandwidth of 9.2%, 22dB F/B and 14.6% impedance bandwidth. By extending, in between the array elements, comb like linear tapered narrow strips from the finite ground plane of the structure, SLL of the basic array improves to -32dB, the 20dB SLL bandwidth become 12.1% while the F/B and impedance bandwidth remains the same as before. To verify the accuracy of the simulation results, both of the arrays are fabricated and tested.
