    • A multi-band antenna comprises a first conductive layer having one or more parasitic patches, a second conductive layer having a plurality of radiating patches, and a third conductive layer having a ground patch. The first, second and third conductive layers may be separated by first and second substrate layers. The second conductive layer may comprise a first radiating patch having dimensions selected to radiate signals within a first frequency spectrum and second radiating patches having dimensions selected to radiate signals within a second frequency spectrum. In wireless local area network (WLAN) embodiments, the first frequency spectrum may comprise a frequency band ranging from approximately 5.1 to 5.9 GHz, and the second frequency spectrum may comprise frequency bands ranging from approximately 2.4 to 2.5 GHz.
    • 多频带天线包括具有一个或多个寄生片的第一导电层,具有多个辐射片的第二导电层和具有接地片的第三导电层。 第一,第二和第三导电层可以由第一和第二衬底层分离。 第二导电层可以包括第一辐射贴片,其具有被选择用于辐射第一频谱内的信号的尺寸,以及具有被选择用于辐射第二频谱内的信号的尺寸的第二辐射贴片。 在无线局域网(WLAN)实施例中,第一频谱可以包括范围从大约5.1到5.9GHz的频带,并且第二频谱可以包括范围从大约2.4到2.5GHz的频带。
