PURPOSE:To improve the antenna gain by providing a shield ground conductor in continuity with the 1st and 2nd ground layers in between and close to a feeder line. CONSTITUTION:The shield ground conductor 9 is provided in continuity with the ground layers 5, 6 and in close to the feeder line 4 in the microstrip antenna provided with dielectric bases 1, 2, 3, the feeder line 4, the 1st and 2nd ground layers 5, 6 and a resonance element 7. Thus, the coupling loss between the antennas due to the radiation loss and spurious radiation of the discontinuous part of the feeder system is eliminated to improve the antenna gain. |
