| Abstract: |
| According to the electromagnetic environment and service requirements in a regio
n of high user density wh
ich requires high efficiency and wideband wireless coverage, an antenna with two
e
lements and selection function is designed by adopting switch selection circuit
and SMT technology. The designed antenna can cover the
whole UMTS(Universal Mobile Telecommunications System) band. The test of the pat
tern of two elements antenna system shows that
the antenna can maintain complementary in space and it has a high stability. |
