Abstract
The present invention provides apparatuses and methods for an antenna in a wireless receiving system. The antenna includes an opened segmented component that is electrically coupled to a printed circuit board and a capacitive top loaded component that provides a capacitive load. The vertical profile of the antenna may be reduced sufficiently so that the antenna may be internally located in the same enclosure as the printed circuit board. The capacitive top loaded component is situated away from a ground plane of a printed circuit board to reduce the capacitive coupling is reduced, and consequently the required voltage standing wave ration (VSWR) is maintained over a broad operating range. The capacitive top loaded component includes a closed shape that provides a capacitive load. In order to tune the antenna to operate with a desired characteristic (e.g., within a VSWR criterion), the closed shape may be modified.
