Abstract
A hollow waveguide (1) has a wall (3) having plural pegs (16) thereon. The pegs (16) which project into the hollow interior of the waveguide (1) such that the waveguide (1) propagates electromagnetic waves only below a certain frequency. The surface of each of the pegs (16) is substantially free of discontinuity and concavities. The waveguide (1) may be manufactured by a moulding process.
Claims10
A hollow waveguide, the waveguide comprising a wall having plural pegs thereon which project into the hollow interior of the waveguide such that the waveguide propagates electromagnetic waves only below a certain frequency, the surface of each of the pegs being substantially free of discontinuity and wherein at least some of the pegs have a substantially elliptical cross-sectional shape.
Transmitter-receiver apparatus, the apparatus comprising:
- at least one antenna for transmitting and receiving signals,
- an electronics module for providing signals to the antenna for transmission and for receiving signals received by the antenna, and
- a hollow waveguide selectively coupling the electronics module to the antenna, the waveguide having a wall having plural pegs thereon which project into the hollow interior of the waveguide such that the waveguide propagates electromagnetic waves only below a certain frequency, the surface of each of the pegs being substantially free of discontinuity and wherein at least some of the pegs have a substantially elliptical cross-sectional shape.
