SINGLE FEED TRI-BAND PIFA WITH PARASITIC ELEMENT |
摘要 |
A Planar Inverted F-Antenna (PIFA) comprising: a radiating element placed above a dielectric carriage with four side walls; a ground plane positioned below the dielectric carriage; a short circuiting element at the front edge of the radiating element; a feed tab at the front edge of the radiating element; vertical planes formed along the right and left edges of the radiating element forming capacitive loading plates; a first reactive loading slot formed in the radiating element between the short circuiting element and the left edge thereof; the open end of the first reactive loading slot being at the front edge of the radiating element; a second reactive loading slot formed in the radiating element between the feed tab and the right edge thereof; the open end of the second reactive loading slot being at the back edge of the radiating element; conductive stubs at the front and back edges of the radiating element for tuning lower and upper resonant frequencies; a conductive strip having a vertical attachment inserted into the dielectric carriage through a slot in the back side wall of dielectric carriage; the conductive strip with its vertical attachment being positioned flush with the outer surface of the back side wall and is connected to the ground plane to serve as a parasitic element to the radiating element for an additional and exclusive resonance.
