- the motherboard 250 has a larger physical area than the antenna device 120, so that the heat dissipation efficiency of the motherboard is higher than that of the antenna device 120. Therefore, in the second embodiment, the FEM 130 arranged on the connecting member 140 is arranged closer to the motherboard 250 than the antenna device 120, so that the heat generated by the FEM 130 can be easily transferred to the motherboard 250.

- the FEM 130 close to the motherboard 250 in the connecting member 140 is not preferable from the viewpoint of loss of transmission power and deterioration of the noise figure (NF) as described in the first embodiment. That is, regarding the installation position of the FEM 130 on the connecting member 140, there is a trade-off relationship between loss reduction and heat dissipation efficiency. Therefore, the position of the FEM 130 on the connecting member 140 is determined in consideration of the degree of heat generation in the FEM 130 and the required antenna characteristics.
