Retractable and pivotable multiple frequency band antenna

A radiotelephone, comprising:

• a radiotelephone housing configured to enclose a radiotelephone transceiver, said radiotelephone housing defining a longitudinal direction;
• a dielectric substrate comprising opposite first and second ends, said second end movably mounted to said radiotelephone housing such that said dielectric substrate has:
• a first extended position such that said dielectric substrate extends along said longitudinal direction;
• a second extended position wherein said dielectric substrate first end is pivoted away from said radiotelephone such that said dielectric substrate extends along a second direction that is transverse to said longitudinal direction;
• and
• a retracted position;
• first and second radiating elements disposed on said dielectric substrate adjacent said first end, said first and second radiating elements configured to resonate within respective first and second frequency bands;
• means for electrically connecting said first and second radiating elements to said transceiver when said dielectric substrate is in said retracted position;
• third and fourth radiating elements disposed on said dielectric substrate between said first and second ends, said third and fourth radiating elements configured to resonate within said first and second frequency bands, respectively;
• and
• means for electrically connecting said third and fourth radiating elements to said transceiver when said dielectric substrate is in said second extended position.
