Dual-Band Dual-Polarized Slot-Coupled Microstrip Antenna for Duplex Applications
2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)(2019)
Abstract
A dual-band dual-polarized slot-coupled microstrip antenna is proposed in this paper. Good isolation between the two input ports and low cross-polarization radiation level are achieved, which are required for duplex applications. The element is designed for operation at 4.1 and 6.6 GHz. By loading short pins, the proposed design exhibits considerable improvement in terms of the gain at higher resonant frequency, cross-polarization level, and impedance bandwidth, compared to the original design. Each design has been fabricated and experimented.
