A data terminal usable with a paging receiver mounted thereon is disclosed. The data terminal includes a whip antenna and a resonance circuit which is connected to the whip antenna. The ground of the resonance circuit is connected to the ground of circuitry mounted in the data terminal so that the ground of the, latter serves as a reflector of the whip antenna to enhance the antenna gain as well as the receive sensitivity. The antenna of the receiver is sufficiently remote from a clock oscillating section for a CPU which is installed in the data terminal whereby clock, noise generated by the clock oscillating section is prevented from deteriorating the receive sensitivity.
