            <description><![CDATA[An inverted-F antenna includes a radiation element, a ground element, a loop conductive pin, a signal feed-in portion, and a signal line. The antenna is designed as the signal feed-in portion and the ground portion sharing a single pin, thus solving the problem of the conventional inverted-F antenna having complicated components and increased cost due to using two independent components in parallel including a conductive pin and a signal feed-in portion for grounding and receiving feed-in signals.]]></description>

            <description><![CDATA[An antenna system comprising a first antenna element, a second antenna element, and a parasitic element, wherein the parasitic element is arranged with regard to the first antenna element and the second antenna element such that a greatest difference in gain between respective antenna patterns of the first and second antenna elements occurs at a null of the pattern of the first antenna element.]]></description>
