Abstract :
A novel internal quadband antenna for radiotelephone handset applications is presented. The design uses a hybrid of ceramic and conventional antenna technologies and shows good efficiency characteristics. With a volume of 3.5cc, the antenna is smaller than current in-service tri and quad band designs. A method of extending the design for diversity or MIMO applications at the higher frequencies is discussed.
