    Abstract: An antenna structure ( 126 ) that includes a Planar Inverted-F Antenna (PIFA) ( 104 ) and an extendable portion such as a whip element ( 106 ). The PIFA ( 104 ) operates normally when the extendable portion ( 106 ) is retracted and upon extension, an electrical contact is made between the extendable portion ( 106 ) and the end ( 122 ) of the PIFA ( 104 ) that is electrically opposite, i.e., furthest along the electrically conductive path of the PIFA, from the feed structure ( 202, 208 ) for the PIFA ( 104 ). The electrical length of the composite antenna ( 126 ) is then substantially equal to the sum of the electrical length of the PIFA ( 104 ) and extendable portion ( 106 ). An embodiment disconnects the ground path of the PIFA feed structure upon extension of the extendable portion ( 106 ) to provide constant input impedance.

    Abstract: A bowtie monopole antenna is fabricated of a sheet metal radiating body 102 that is triangular shaped, and having a longitudinal dimension and axis (106) and a width (108). One corner of the radiating body is tapered to form a feed point (104). The length dimension determines the antenna's lowest resonance frequency while the taper created by the width determines the highest point of resonance. For using the bowtie monopole antenna in a communication device, the radiating body (102) is folded or wrapped around towards itself. To facilitate the folding or wrapping a mounting substrate (202) is used. The substrate may be provided with retaining features (206) to capture the antenna assembly within the communication device.

    Abstract translation: 蝴蝶结单极天线由三角形且具有纵向尺寸和轴线（106）和宽度（108）的金属片散热体102制成。 辐射体的一个角部渐缩以形成馈电点（104）。 长度尺寸决定天线的最低共振频率，而由宽度产生的锥度决定共振的最高点。 为了在通信设备中使用领结单极天线，辐射体（102）被折叠或朝自身缠绕。 为了便于折叠或包装，使用安装衬底（202）。 衬底可以设置有保持特征（206）以捕获通信装置内的天线组件。
