Abstract
This letter presents two dual-band (DB) low-profile antenna designs for Ka-band applications, integrating a hybrid structure of a DB-patch and a DB-half-mode substrate integrated waveguide resonator fabricated using through-glass vias (TGVs) technology. The proposed designs achieve DB operation with enhanced bandwidth and gain, all within a single-layer substrate to maintain a compact profile. Ant.1 employs a dual-cavity configuration, while Ant. 2 utilizes a single cavity supporting $\text{TE}_{101}$ and $\text{TE}_{301}$ mode. A prototype of Ant. 1 was fabricated and tested to validate the design. Measurements demonstrate a −10 dB impedance bandwidth of 25.58 GHz to 28.26 GHz (10%) for the lower band and 36.83 GHz to 38.94 GHz (5.5%) for the higher band, with peak gains of 6.1 dBi and 5.6 dBi, respectively. Compared to existing designs, Ant. 1 achieves a lower profile (0.04 $\lambda _{0}$) in the Ka band while maintaining competitive performance. This work offers a promising solution for compact and efficient DB antennas in Ka-band communication systems.
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.
