Abstract

Radiotelephones include flat blade antennas and flip configurations. The flat blade antenna and flip are mounted to the radiotelephone via dual hinges. The flat blade antenna is configured to be captured by the flip to define a cover in the stow position. The flat blade antenna rotates separate from the flip. The flat blade antenna opens to an angular position greater than the adjacently mounted flip.
