Abstract :
A frequency-tunable and switched beam antenna is proposed. Variable capacitances are loaded to monopole antenna elements and switch the radiation beam as well as the frequency band. Numerical results of the frequency band and beam pattern of the proposed antenna are shown with varying the value of variable capacitances.
