1. A multifrequency antenna for a wireless communications system comprising:
- a metallic plate comprising a ground strip and an elongated slot;
an elongated conductive feed strip attached to the metallic plate and extending lengthwise within and across at least a portion of a width of the slot;
a first elongated conductive strip attached to the metallic plate and extending lengthwise within and across at least a portion of the width of the slot;
a second elongated conductive strip attached to the first elongated conductive strip and extending lengthwise within and across at least a portion of a length of the slot; and
a feedline connected to the conductive feed strip for feeding radio signals to the feed strip and for receiving radio signals from the feed strip.

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.
