Abstract

In a portable radio communication apparatus comprising a handset (20) having a side surface (23) and a recessed surface (24), first and second antennae (51 and 52) of different resonance frequencies are fixed to the recessed surface by first and second conductive plates (55 and 56), respectively. First and second conductive lines (61 and 62) connect a common conductive line (63) to the first and the second antennae, respectively. The common conductive line is connected to an electro-audio and audio-electro converting device (30) to feed a transmitting electric signal to the first and the second antennae and to receive the received electric signal from the first and second antennae. The first and the second antennae have first and second antenna widths (W.sub.1 and W.sub.2), respectively. The first and the second conductive plates have first and second plate widths, respectively, and first and second axes centrally of the first and the second plate widths, respectively. The first and the second plate widths are not greater than the first and the second antenna widths, respectively. The first and the second axes are spaced wider than a half of a sum of the first and the second antenna widths.
