The slot array antenna is used for pattern- critical applications including satellite communications and radar. In most mobile communications antennas, the pattern detail at the mobile terminal is not critical because of the distributed target of a multipath propagation environment. Motivated by a need for bicycle connectivity, this paper looks to waveguide-excited slot antennas on the bicycle frame. The idea is to have a radio mounted internally and radiating from of multiple slots distributed along the frame. The main drawbacks of waveguide slot arrays is their bandwidth sensitivity to dimensional variations; and in the case of a bicycle frame, there is variability in the waveguide cross section, length, and in bends along the waveguide. The use of slots on the different facets of the waveguide are shown to improve the bandwidth and help compensate for the frame length variability.
