General information
- Short Summary
- Double Differential Fed, Dual Polarized Patch Antenna with 90 dB (decibel) Interport RF (Radio frequency) Isolation for 2.4GHz In-Band Full Duplex Transceiver
- Full Description
-
This technology presents a 2.4 GHz, dual-polarized microstrip patch antenna with extremely high interport isolation for a shared antenna architecture-based in-band full-duplex transceiver. The presented antenna configuration is based on four-ports linearly polarized single radiating element with differential feeding for both transmit (T) and receive (R) operation. The double-differential feeding using two identical 3 dB/180° ring hybrid couplers with nice amplitude and phase balance effectively suppresses the interport RF leakage to achieve very high isolation. The prototype of the proposed antenna architecture is implemented using a 1.6 mm thick general-purpose FR-4 (flame retardant) substrate. The implemented antenna provides more than 90 and 80 dB interport RF isolation for 20 and 40 MHz (megahertz) bandwidths, respectively, in addition to more than 98 dB port-to-port peak isolation when measured inside an anechoic chamber. To the best of our knowledge, this is the highest amount of RF isolation reported for a single dual-polarized patch antenna.
