A linearly polarized array antenna with radial waveguide for L-band was put forward, which can realize rotundity array antenna based on triangle grid. The multilayer radial waveguide and a horizontal ring antenna was researched, then the L-band linearly polarized array antenna with the array element space of less than one wavelength. The results indicate that this structure is feasible to realize the linearly polarized radial waveguide array antenna; the antenna gain is 19.97 dBi, the axial ratio is -52.06 dB and the reflection coefficient is 0.105 2 at 1.57 GHz; In the range of 1.37 GHz to 1.77 GHz , the gain is over 18.64 dBi and the axial ratio is below -46.45 dB.
