Abstract
A multifrequency antenna for a wireless communications system includes a metallic plate having a slot. The slot is used for transmitting and receiving radio signals of a first frequency band. The length of the slot corresponds to the first frequency band at which signals are transmitted and received. The antenna also includes a metallic strip connected to the metallic plate for transmitting and receiving radio signals of a second frequency band. The metallic strip may be formed as an L-shaped strip. The length of the horizontal portion of the L-shaped strip corresponds to the second frequency band at which signals are transmitted and received.
Claims19
A multifrequency antenna for a wireless communications system comprising:
- a metallic plate having a slot defining a slot antenna for transmitting and receiving radio signals of a first frequency band;
- and
- a metallic strip connected to a section of the metallic plate around the slot for transmitting and receiving radio signals of a second frequency band.
A multifrequency antenna for a wireless communications system comprising:
- a conductor layer having a resonance opening defining a slot antenna for transmitting and receiving radio signals within a selected frequency range;
- and
- at least one radiation conductor connected at one end with the conductor layer around the opening thereof and having a resonance conductor portion for transmitting and receiving radio signals outside the selected frequency range.
A multifrequency antenna for a wireless communications system comprising:
- a conductive plate, having a slot defining a slot antenna for transmitting and receiving radio signals of a selected frequency band, and forming at least one conductive strip extending from a section of the conductive plate around the slot for transmitting and receiving radio signals outside the selected frequency band by creating resonance in the conductive strip.
