A battery powered TDM (or combined TDM/FDM) communication device (104, 105) operates within a TDM communication system (100) having a communication channel arranged into repetitive time frames (401) each having a plurality of slots. At least two of these slots (404) are allocated for communicating signalling and control information. To conserve energy, the battery powered communication device operates in a first mode (i.e., the energy saving mode) to shut down non-essential circuits for a predetermined time interval, awaking to monitor only one of the two control slots. In this way signalling and control information may be received. When not operating in the energy saving mode, the battery powered communication device operates in a second mode (i.e., a fast access mode) to monitor both of the control slots (404).

The molded resonator includes at least one formed resonator element having an resonator portion and opposed end leg portions which provide electrical connections to the main portion. A dielectric portion is molded about the resonator element. A conductive ground plane is carried by the dielectric portion and electrically shields the resonator element. The resonator element is formed of wire having a circular cross-section.
