Antenna assembly for a communication system

A communication system comprising:

• an antenna assembly having an antenna element and a transmission line, the antenna element having a substrate and a dual dipole antenna circuit electrically coupled to the transmission line, the substrate extending between a top end and a bottom end, the substrate having a first side and a second side between the top end and the bottom end, the substrate having a first surface and a second surface, the dual dipole antenna circuit being provided at least on the first surface, the transmission line terminated to the antenna element at the first surface;
• and
• a housing having a cavity receiving the antenna assembly, the housing including an upper shell having a top wall and a lower shell having a bottom wall, the upper shell having side walls and end walls extending between the top wall and an inner end opposite the top wall, the lower shell having side walls and end walls extending between the bottom wall and an inner end opposite the bottom wall, the inner end of the upper shell meeting the inner end of the lower shell at an interface, the upper shell including an upper strain relief component on the first side at the inner end, the lower shell including a lower strain relief component on the first side at the inner end aligned with the upper strain relief to define a channel receiving the transmission line, the upper shell having an upper mounting lug on the top wall engaging and holding the top end of the substrate, the lower shell having a lower mounting lug on the bottom wall engaging and holding the bottom end of the substrate, the upper and lower mounting lugs being offset from the upper and lower strain reliefs to align the first surface with the channel.

• wherein the transmission line is routed between the substrate and the channel such that the transmission line interior of the housing is positioned generally equidistant from the low-band feed terminal and the low-band ground terminal and is generally equidistant from the high-band feed terminal and the high-band ground terminal, the transmission line being routed exterior of the housing such that the transmission line exterior of the housing is positioned closer to the low-band ground terminal than the low-band feed terminal and such that the transmission line is positioned closer to the high-band ground terminal than the high-band feed terminal.
