Millimeter-wave Near-field Spectrum Analyzer Based on Integrated Side-fire Antennas
A real-time, low-profile and shielded spectrum analyzer is proposed for operation at mm-wave frequencies based on Substrate Integrated Waveguide (SIW) technology. A novel unit cell is also proposed to enable an in-plane side-fire radiating Leaky Wave Antenna (LWA). The unit cell is inspired from a conventional T-junction and is equipped with an internal matching mechanism to suppress stop-band to achieve full-space radiation. The antenna characteristics and the system operation is confirmed using full-wave simulations. The proposed system is analog, broadband, real-time in nature, low-profile and compact in size; ideal for instrumentation applications.
