RESONANT FREQUENCY TUNABLE ANTENNA APPARATUS |
摘要 |
In a tunable antenna apparatus, a dielectric block is mounted on a printed circuit board. A radiation pattern has a feeding part formed on the dielectric block and connected commonly to a feeding source and a variable DC power. Also, a connecting pattern extends from the radiation pattern onto the printed circuit board. In addition, at least one tuning pattern is formed on the printed circuit board and connected in series to the connecting pattern via at least one switching device.
