Abstract

Tunable antennas are very promising for future generations of mobile
communications, where antennas are required to cover a wide range
operating bands. This letter aims at characterizing the loss mechanism
of tunable antennas. Tunable antennas typically exhibit a high Quality
factor (Q), which can lead to thermal loss due to the conductivity of the
metal. The investigation shows that copper loss is non-negligible for high
Q values. In the proposed design the copper loss is 2 dB, for a Q of 260 at
700 MHz.
