ABSTRACT:
An improved miniature antenna is disclosed which provides an electrically short radiation pattern by providing shielding of selected portions of a current carrying conductor forming a loop antenna. The shielding is provided so that the shielded portion of the loop antenna does not cancel the radiation from an unshielded radiating portion of the antenna, thereby producing a uniform radiation pattern. A plurality of the current carrying elements formed by the shielded and unshielded portions may be coupled in a series and parallel relationship to provide optimum impedance matching at the frequency of operation of a transmitter or receiver.
