Summary: In this article, a high-gain millimeter-wave transmitarray antenna (TAA) with scanning ability is developed using an array feed as the primary emitter. The addition of defocused phases to the phase distribution of the lens enables energy dispersion into the scanning scope. The proposed beam forming algorithm improves the scanning capability of the transmitarray. A transmitarray based on square waveguide elements achieves a high gain of 37.95 dBi at 160 GHz, despite a 2.2 dB error compared to the calculation in the operating band of 150-170 GHz. The transmitarray demonstrates its potential for generating scannable high-gain beams in the millimeter-wave band.

Summary: This communication proposes a shared structure (SS) antenna design that operates in S/C/K/Ka bands. Resonances in S and C bands are achieved using a stepped impedance slot antenna, which also serves as the ground plane for the K/Ka bands antenna. A novel feed structure is designed to excite three patch elements working at 24, 26, and 28 GHz in the K/Ka bands. The design is compact and accommodates multiple frequency bands, making it suitable for various applications in wireless communication.

Summary: A single-layer dual-/tri-band substrate integrated waveguide (SIW) filtenna based on multifunctional cavity-backed slots is proposed. The cavity-backed slots can function as radiators and resonators. By designing a pair of back-to-back open-loop slots embedded with a straight slot on the SIW cavity, three resonant modes combine with the TE101 mode to achieve superior dual-band filtering performance. Furthermore, four radiation nulls located at the sides of the operational passbands result in sharp roll-offs and deep stopband rejection.
