“…This leads to poor process consistency and increased complexity and cost. References [13][14][15][16][17] used devices such as PIN diodes and Varactor diodes to reconfigure the antenna pattern. These antennas have large reconfigurable angles of the pattern but their length and width are generally above 10 mm and therefore cannot adapt to the trend of device miniaturization.…”

The research on reconfigurable antennas has some disadvantages such as low working frequency and large size. This paper presents a Ka-band patch antenna with pattern reconfigurability using RF MEMS switches. The antenna contains one main patch, two sub-patches, two parasitic patches, and two RF MEMS switches. By controlling the states of the RF MEMS switches, the antenna can achieve three different radiation patterns (−8°, 0°, and +8°) at 35 GHz. The pattern analysis was based on the electric field vector addition method. The analytical, simulated, and measured results agree well with each other. Due to its compact and thin structure of 3.7 mm × 5.2 mm × 0.4 mm, this antenna can be applied in fields such as satellites, smartphones, etc.

“…Thus, the implementation of a pattern reconfigurable antenna with a low profile can alleviate those constraints. To date, many pattern reconfigurable antennas [1,2,3,4,5] have been developed, and reconfigurable antennas are commonly implemented using variodes [6,7] and PIN diodes [1,2]. Compared with the variodes, PIN diodes, and other technologies, radio frequency (RF) micro-electromechanical systems (MEMS) switches possess many attractive advantages, such as high linearity, high quality factors, and almost no Please check the sections highlight in yellow in “the whole text” as we have made little modification.…”

In this paper, a silicon-based radio frequency micro-electromechanical systems (RF MEMS) pattern reconfigurable antenna for a Ka-band application was designed, analyzed, fabricated, and measured. The proposed antenna can steer the beam among three radiating patterns (with main lobe directions of −20°, 0°, and +20° approximately) at 35 GHz by switching RF MEMS operating modes. The antenna has a low profile with a small size of 3.7 mm × 4.4 mm × 0.4 mm, and consists of one driven patch, four parasitic patches, two assistant patches, and two RF MEMS switches. The active element pattern method integrated with signal flow diagram was employed to analyze the performances of the proposed antenna. Comparing the measured results with analytical and simulated ones, good agreements are obtained.
