| 发明名称 | Combination antenna | ||
| 摘要 | Combination antenna, which comprises two different antenna parts, of which the first antenna part is fitted to operate at a lower frequency range and the second antenna part is fitted to operate at a higher frequency range. The second antenna part of the combination antenna is arranged above the first antenna part. The supply cable of the second antenna part (102) of the combination antenna is arranged to travel in connection with the first antenna part. The first antenna part comprises two or more radiator parts (104, 106, 108) and also coils (112) between them, wherein the coil or coils (112) are formed from the supply cable of the second antenna part (102). | ||
