Wireless connectors and communication systems are described including a first communication device configured to emit a modulated signal, a second communication device configured to receive the emitted modulated signal and a waveguide disposed between the first and second communication devices and configured to wirelessly receive the emitted modulated signal from a first end of the waveguide, guide the received signal from the first end to an opposite second end of the waveguide, and wirelessly transmit the guided signal from the second end to the second communication device. In some embodiments, the telescopic waveguide includes a plurality of guiding sections, each guiding section being configured to slide within or over an adjacent guiding section inwardly to reduce a length of the telescopic waveguide and outwardly to increase the length of the telescopic waveguide.
