Abstract
An antenna utilizes multiple radiating elements placed at regular interval around a geometric structure. Each of the individual radiating elements are selectably activated in order to narrow the range of transmission and reception for the antenna. Larger antenna gain is achieved by narrowing the radiation pattern and each individual radiating element has significantly more gain than an omni-directional radiator while also reducing the power output requirements of the transmitter.
Claims39
An apparatus comprising:
- a monopole antenna coupled to a portable communications device;
- a plurality of radiating elements mounted on said monopole antenna;
- control circuitry to select a subset of said plurality of radiating elements;
- switching circuitry to activate said selected radiating element subset;
- and
- a plurality of feeds coupled to the switching circuitry, wherein each of said radiating elements is coupled to one of said feeds.
