A novel millimeter-wave (mm-wave) amplitude-only direction finding (DF) antenna front-end is proposed and experimentally demonstrated based on multiport leaky-wave antennas (LWAs). The multiport LWA is realized using an array of $N$ linearly polarize

In this paper, we present an experimental study evaluating the performance of a reconfigurable antenna element for direction-of-arrival (DOA) estimation in wireless systems. We consider a reconfigurable antenna with directive radiation pattern and an

Bessel beams are proposed as a practical way to generate well collimated and confined beams at mm-waves or THz for quasi-optical applications. To achieve that, we propose the use of two-dimensional antenna arrays as realizable launchers. Truncated Be

A composite right/left-handed (CRLH) leaky-wave antenna (LWA) with polarization diversity using equalized common-mode (CM) and differential-mode (DM) responses in terms of S-parameters and radiation patterns is presented. Compared to a previous work,

In this work, the mixed-mode approach is employed to characterize the modal parameters of a newly-invented circularly-polarized (CP) composite right/left-handed (CRLH) leaky-wave antenna (LWA). The single-ended CP-LWA is comprised of two coupled CRLH

A novel real-time spectrum analyzer (RTSA) is presented. This RTSA exploits the frequency-space mapping property of the composite right/left handed (CRLH) leaky-wave structure to generate spectrograms with unrestricted time-frequency resolution, not
The propagation and radiation properties of dual composite right/left-handed (D-CRLH) transmission line metamaterials are presented, and validated experimentally with a 1D microstrip prototype. In its fast-wave regime, this structure operates as a le
