1. A radio frequency identifying device comprising:
- a radio frequency sensor for sensing whether there is an radio frequency tagged identification object within a predetermined area;
an antenna device comprising an antenna operably connected to both an antenna plate and a vibration motor, and a controller controlling the vibration motor and the antenna plate, wherein the controller, upon the identification object being sensed by the sensor, controls the vibration motor to physically vibrate the antenna plate along at least one axis while radiating a radio frequency radiation pattern to the radio frequency tagged object to create a vibrated radio frequency radiation pattern, and wherein said vibrated radio frequency radiation pattern has reduced null zones than said radiated radio frequency radiation pattern that was not vibrated.

9. An antenna device of a radio frequency identifying device, comprising:
an antenna plate operable to radiate a radio frequency radiation pattern;
a vibration motor operable to generate vibration along at least one axis, said vibration vibrating the antenna plate while said radio frequency radiation pattern is being radiated;
a vibration plate operable to transmit the vibration to the antenna plate, wherein the vibrated radio frequency radiation pattern is radiated when a radio frequency sensor senses the presence of a radio frequency tagged identification object within a predetermined range; and
wherein the vibrated radio frequency radiation pattern has reduced null zones than said radiated radio frequency radiation pattern that was not vibrated.- View Dependent Claims (10, 11)
