A resonating apparatus in accordance with the present invention comprises a dielectric resonator on a dielectric supporting substrate, a fluid dielectric membrane which overspreads the dielectric resonator, and a microstrip line which is arranged in the fluid substrate membrane so that it is coupled with the dielectric resonator. In example embodiments, an indication to record serial events including a first event and a second event on a same channel is received. The antenna can use an inflatable collapsible transreflector.
