Abstract
An antenna unit for use in a mobile telecommunications network, which is capable of transmitting and receiving radio signals from the inside of buildings to and from mobile terminals operating in the network. The antenna also prevents the radiation levels within the building from rising above approved safe levels thereby allowing occupiers of the building to continue working in areas adjacent the antenna. Furthermore, the antenna can be located in areas having a large proportion of listed or protected buildings.
Claims8
An antenna unit, comprising a housing locatable on the inside of an external portion of a building and an antenna mounted inside the housing,
- characterised in that:
- the unit is arranged such that, when located on the inside of an external portion of a building,
- (i) substantially no dielectric material is disposed between the antenna and the external portion;
- and
- (ii) the antenna is spaced from the external portion to substantially prevent reflected radiation from the external portion interfering with radio signals transmitted by the antenna.
An antenna unit according to any preceding claim, wherein the spacing between the antenna and the external portion is between 3 cm and 10 cm.
