1. A mobile terminal comprising:
an antenna apparatus including:
an antenna radiator disposed at a first end of the mobile terminal;
at least one antenna modifying element disposed at a second, opposing end of the mobile terminal; and
a coupling means for detachably physically fastening the first end of the mobile terminal with the antenna radiator disposed therein and the second end of the mobile terminal with the at least one antenna modifying element disposed therein and electrically connecting the at least one antenna modifying element with the antenna radiator when the first and second ends are fastened;
wherein the antenna modifying element changes an operational configuration of the antenna apparatus from one of:
a monopole antenna to an inverted F antenna;
an inverted F antenna connected at a point thereof to a ground surface, to an inverted F antenna connected at least at one additional point thereof to a ground surface;
a monopole or inverted F antenna having a first radiator to a monopole or inverted F antenna having at least one additional radiator; and
a first part including a first monopole or inverted F radiator connected to a first signal source or receiver set to a first operating frequency, to a connected configuration of the first part with a second part that includes a second monopole or inverted F radiator connected to a second signal source or receiver set to a second operating frequency.
