A Design of V-band Reconfigurable SPDT Switch/Power Divider Based on Slotted SIW

Abstract

In this paper, a novel reconfigurable single-pole double-throw (SPDT) switch/power divider (PD) employing substrate-integrated waveguide (SIW) technology is presented for V-band applications. By controlling the dc-bias of PIN diodes, the proposed reconfigurable function can be achieved. Simulations show that, when functioned as a SPDT switch, the circuit exhibits an isolation of larger than 32 dB and an insertion loss of less than 1.4 dB from 58-62 GHz. On the other hand, a minimum insertion loss of 0.9 dB is calculated at 60 GHz when functioned as a 3-dB PD. The total area of the device is 3λ0 × 2.36λ0.
