Thefirst antenna structure 28 is formed by insulating the opposite sides of thespacer 24, and asecond antenna structure 29a corresponding to thesecond antenna layer 29a is formed on a part of the surface of theadhesive layer 91 on thesecond side 20b of thecarrier structure 20.Antenna body 29b, to form thesecond antenna structure 29 by keeping a distance between thesecond antenna body 29b and thesecond antenna layer 29a, and make thesecond antenna body 29b surround thefirst antenna body 28b, as shown in Figure 2F.

於本實施例中，以6吉赫(GHz)頻段為界線，該第一天線結構28係為高頻段天線，即高於6GHz，且該第二天線結構29係為低頻段天線，即6GHz以下(俗稱Sub-6GHz)。例如，該電子元件21藉由該第一天線結構28收發24~53吉赫(GHz)頻率之高頻5G毫米波(mmWave)訊號，且該電子元件21藉由該第二天線結構29收發Sub-6GHz(約410~7125兆赫(MHz))頻率之低頻5G毫米波訊號。In this embodiment, taking the 6 GHz frequency band as the boundary, thefirst antenna structure 28 is a high-frequency band antenna, that is, higher than 6 GHz, and thesecond antenna structure 29 is a low-frequency band antenna, that is, Below 6GHz (commonly known as Sub-6GHz). For example, theelectronic component 21 transmits and receives high-frequency 5G millimeter wave (mmWave) signals at a frequency of 24 to 53 gigahertz (GHz) through thefirst antenna structure 28, and theelectronic component 21 transmits and receives high-frequency 5G millimeter wave (mmWave) signals through thesecond antenna structure 29.

另外，可藉由濺鍍(sputtering)、蒸鍍(vaporing)、電鍍、無電電鍍、化鍍或貼膜(foiling)等方式製作第一天線體28b與第二天線體29b。In addition, thefirst antenna body 28b and thesecond antenna body 29b can be fabricated by sputtering, vapor deposition, electroplating, electroless plating, electroless plating, or foiling.
