Title:
Reconfigurable Antenna Array Using the PIN-Diode-Switched Printed Square Spiral Element
Report Date:
2021-10-26
Abstract:
A dual-band array of reconfigurable elements is modeled and simulated. The array consists of four single square spiral microstrip antennas that are corporately fed and are used as a unit cell. The single square spiral uses two PIN diodes as switching elements to achieve reconfiguration. The array has four switch states that can operate over four discrete frequencies in the S and C bands. The unit cell radiation pattern is used with the pattern multiplication model to quickly simulate the array pattern of larger arrays. A 3 x 3 array of the unit cells is modeled with only the center element active and designated as the embedded unit cell. The embedded unit cell is used to capture the effects of mutual coupling and to see how significantly the coupling affects the radiation patterns. The effects of mutual coupling are found to be negligible for a 2 x 2 and larger sized arrays.
