First Claim
Patent Images
1. A portable communications device comprising:
- a case operable to be held in a user'"'"'s hand;
a grounding element;
an antenna mounted within the case in operative relation to the grounding element and operable to both radiate and receive electromagnetic waves across at least one industry-standard frequency band;
wherein the antenna comprises;
a radiating element disposed relative to the grounding element in a monopole configuration and comprising a first part and a second part;
wherein the first part comprises at least one conducting surface;
wherein the second part comprises a loading structure;
wherein the loading structure comprises at least one conducting strip connected at least two points on an edge of the at least one conducting surface;
wherein the maximal width of the at least one conducting strip is less than a quarter of the longest straight edge of the at least one conducting surface; and
wherein the loading structure causes the antenna to radiate and receive electromagnetic waves across at least one more industry-standard frequency band compared to an identical antenna without the loading structure.

Abstract
A novel loaded antenna is defined in the present invention. The radiating element of the loaded antenna consists of two different parts: a conducting surface and a loading structure. By means of this configuration, the antenna provides a small and multiband performance, and hence it features a similar behavior through different frequency bands.
