MULTIBAND ANTENNA SYSTEM

摘要

An antenna enables compact and robust multiband operation of portable radios. According to some embodiments, the antenna includes: a first rolled conductive strip having a first section with overlap between successive turns of the first conductive strip and a second section with no overlap between successive turns of the first conductive strip, the first section having an insulating layer between the overlapping successive turns of the first conductive strip; a second rolled conductive strip; and a flexible sheet to which both the first conductive strip and the second conductive strip are bonded.

1. A multiband antenna system, comprising:
a printed circuit board (PCB); a low frequency (LF) matching circuit operatively connected to the PCB, the LF matching circuit having a radio port and a distal port; a high frequency (HF) matching circuit operatively connected to the PCB, the HF matching circuit having a radio port and a distal port; a stripline operatively connected to the PCB, the stripline providing a common ground for the HF and LF matching circuits; a first radiator element operatively connected to the distal port of the LF matching circuit and to the distal port of the HF matching circuit; and a second radiator element operatively connected the radio port of the LF matching circuit or to the radio port of the HF matching circuit.
