Abstract
An communication terminal for radio communication has an antenna including a PIFA structure being provided with a ground plane element, at least one radiating element, and feeding means for connecting a signal path from a transceiver of the terminal to said at least one radiating element. The antenna comprises a conducting plate element arranged to be substantially in parallel with said PIFA structure. The conducting plate element is electrically floating in relation to said at least one radiating element.
Claims23
An antenna including a PIFA structure comprising:
- a ground plane element,
- at least one radiating element, and
- feeding means for connecting an RF connection to said at least one radiating element,
- wherein said antenna furthermore comprises a conducting plate element arranged to be substantially in parallel with said PIFA structure, and said conducting plate element is electrically floating in relation to said at least one radiating element, the conducting plate element being provided along the PIFA structure adjacent to said at least one radiating element, the distance between the conducting plate element and said at least one radiating element being smaller than the distance between the ground plane element and said at least one radiating element.
An communication terminal for radio communication and having an antenna, and including a PIFA structure comprising:
- a ground plane element,
- at least one radiating element, and
- feeding means for connecting a signal path from a transceiver of the terminal to said at least one radiating element,
- wherein said antenna furthermore comprises a conducting plate element arranged to be substantially in parallel with said RIFA structure, and said conducting plate element is electrically floating in relation to said at least one radiating element, the conducting plate element of the antenna being provided along the PIFA structure adjacent to said at least one radiating element, the distance between the conducting plate element and said at least one radiating element being smaller than the distance between the ground plane element and said at least one radiating element.
A method of reducing the detaining sensitivity of an antenna, including a PIFA structure being provided with a ground plane element, at least one radiating element, and feeding means for connecting a signal path from a transceiver of the terminal to said at least one radiating element, comprising:
- placing a conducting plate element substantially in parallel with said PIFA structure;
- and
- allowing said conducting plate element to be electrically floating in relation to said at least one radiating element,
- wherein the conducting plate element is provided along the PIFA structure adjacent to said at least one radiating element, the distance between the conducting plate element and said at least one radiating element being smaller than the distance between the ground plane element and said at least one radiating element.
