The vector network analyzer (VNA) is the core instrument for S-parameter measurements in microwave and millimeter-wave bands. Frequency extension modules are indispensable for high-frequency testing, in which the directivity of the directional coupler directly determines the reflection measurement accuracy. To address...
A 220 GHz integrated sensing and communication (ISAC) system based on orthogonal-polarization multiplexing is presented for simultaneous high-speed wireless communication and radar ranging. To achieve broadband operation, low insertion loss, and high polarization isolation, a dual-symmetric reverse-coupled orthomode tr...
