发明名称 Retractable antenna assembly with connector
摘要 A retractable antenna assembly with connector (200) allows communication devices that require the use of more than one type of antenna element (114), to easily store the normally used antenna element (114) inside of a housing (134) which is part of the antenna assembly (200). Once inside the housing (134), the antenna element (114) forms a half wave cavity that has a high impedance at the operating frequency of the communication device (302), thereby operatively decoupling the antenna element (114) from the radio frequency path. Once inside of housing (134), antenna element (114) forms part of a coaxial connector (112) with the top portion (116) of antenna element (114) forming the center conductor of the coaxial connector (112). Thereby allowing for an external antenna element (308) to be attached to the communication device (302).
