Abstract
In a short-range on-vehicle radio communication system having in-car radio communication function, a two-way transmission antenna for radio communication is arranged at a panel portion outside a sheet metal chassis of a car navigation unit. As a result, the communication area becomes large, signals including those from a cellular phone of low radio communication output power are easily received, and it is possible to save manufacturing cost.
