Wireless handheld devices, radiation systems and manufacturing methods

A radiation booster apparatus for enabling a radiating structure to transmit and receive electromagnetic wave signals in a frequency region, the radiation booster comprising:

• a unitary dielectric element comprising a substantially polyhedral form factor;
• a first radiation booster comprising:
• a first conductive element disposed on a first portion of a first face of the dielectric element;
• a second conductive element disposed on a first portion of a second face of the dielectric element;
• and
• a third conductive element disposed in at least one via hole through the dielectric element and connecting the first and second conductive elements;
• and
• a second radiation booster comprising:
• a fourth conductive element disposed on a second portion of the first face of the dielectric element;
• a fifth conductive element disposed on a second portion of the second face of the dielectric element;
• and
• a sixth conductive element disposed in at least one via hole through the dielectric element and connecting the fourth and fifth conductive elements.
