Abstract
A passive radio repeater is built into a cover for a pit, in order to relay radio signals between a base station and a wireless communications device such as a water meter at the bottom of the pit. Within the external surface of the lid are provided upper and lower patch antennas. The lower antenna has a radiation pattern that extends downwards at right-angles to the plane of the lid, so that it communicates with the device at the bottom of the pit. The top antenna has a directional beam pattern in the elevation plane, achieved by exciting the top antenna in a mode that is higher than fundamental. The two antennas are coupled by a stripline printed circuit board provided with feeds to generate the required beam patterns.
