Abstract
This paper presents a wideband switched-beam array antenna without using phase shifter. The wideband switched-beam Yagi antenna is used as the array element. The PIN diodes are applied as the RF switches to switch the beam of the antenna. Two-element array of wideband switched-beam Yagi antennas is proposed to provide the 360° switched-beam direction for the short range radar (SRR) system. The simulated results show that the bandwidth of 500 MHz (0.92 - 1.42 GHz) can be obtained, the gain is higher than 4 and 5 dBi at lower and upper frequencies, respectively.
