ANTENNA AND PORTABLE RADIO COMMUNICATION UNIT

摘要

An antenna that achieves a reduction in the thickness and miniaturization of the overall size and that achieves a further increase in bandwidth and a portable radio communication apparatus using the antenna are provided. In an antenna 1, a feeding radiation element 3 and a first non-feeding radiation element 4 that are loaded with dielectric substances are provided on a ground electrode 2, and a second non-feeding radiation element 5 is disposed such that almost the entire second non-feeding radiation element 5 projects outside from a predetermined side 2a of the ground electrode 2. More specifically, each of the three electrode elements 3, 4, and 5 is loaded with a dielectric substance, and a radiation electrode 13 of the second non-feeding radiation element 5 is electrically connected substantially at a central position 2b of the predetermined side 2a of the ground electrode 2 via a connection wire 14.
