A replaceable battery cover can be detachably mounted on a battery storage portion formed in the housing of mobile terminal equipment. A linear or plate-like antenna conductor having an antenna element pattern is joined to the inner surface of the battery cover by using one of joining means including embedding, boding, welding, and fitting means. The battery cover is mounted on the storage portion to electrically connect the antenna conductor to a radio circuit in the housing. In this case, by changing the arrangement of the antenna conductor, the antenna can be replaced with a loop antenna, a zigzag antenna, a helical antenna, or a microstrip antenna in accordance with a specific battery cover. In addition, the device may have an external antenna connection terminal to which an external antenna can be connected or an external interface section.
