Abstract

The microwave (MW)/millimeter-wave (MMW) shared aperture technique is a promising approach to support different frequency bands within limited space. In this letter, a 1 × 4 beam-scanning linear antenna array operating at the MMW (28/39 GHz) band and a vehicle-to-everything (V2X) (5.9 GHz) patch antenna are integrated to share the same aperture. Not only are the entire MMW bands covered, but also the mutually enhanced characteristic between the MW and MMW bands is achieved with the slot-loaded patch. The MW patch nested outside of the MMW radiators can enhance the gain and extend the beam-scanning angles of the MMW antenna array. Furthermore, the hollowed space reserved for MMW antenna can improve the radiation pattern of the MW patch TM₂₁ mode. The proposed tri-band antenna was fabricated and measured. Measured results show that the MMW antenna can cover the bandwidths of 24.4 GHz to 29.3 GHz/36.7 GHz to 41.4 GHz, with the peak gains of 11 dBi/11.3 dBi at 28 GHz/39 GHz frequency bands, while the proposed MW antenna achieves a bandwidth of ∼170 MHz with a peak gain of 8.03 dBi.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
