ABSTRACT:
The present invention relates to antennas for radio signal frequencies, an electromagnetic shield and a mechanical package for electronic components. The antenna uses a three-dimensional conductive structure to enclose the components that are used for the transmission and reception of wireless devices. This conductive structure preferably encloses electronic components. The structure can be divided into two or more sections such that each section is enclosed providing shielding from external electromagnetic fields. Each conductive section is connected to the antenna port or ports of the device it contains. The conductive mechanical package is preferably sized to resonant at the desired frequency of operation. If the electromagnetic fields to be radiated are within and outside the package, the internal bulkheads can be used to control the desired resonant modes. Photonic band gap structures can be also used to connect the pole elements.
