The design and experiment of a single-layer reconfigurable bidirectional antenna are
presented for the first time, which combines the dynamic radiation characteristics of both …

Smart antennas have received great attention for their potentials to enable communication
and perception functions at the same time. However, realizing the function synthesis …

Loading effects of radiating discontinuities have been explored to increase the phase
constant'frequency sensitivity of leaky-wave antennas (LWAs), based on which a quasi …

Leaky-wave antenna (LWA), as a special kind of waveguiding structure simultaneously
characterized by both the guidance and radiation of electromagnetic waves along it, has …

For many leaky-wave antennas (LWAs), it is challenging to realize beam scanning through
broadside. A problem is the presence of an open stopband (OSB), which restricts radiation …

A planar periodic leaky-wave antenna (PLWA) with continuous backward-to-forward beam-
scanning capability and consistent gain is presented. The PLWA is made of a new type of …

A composite right/left-handed (CRLH) leaky-wave antenna (LWA) can effectively scan the
radiation beam from backward-to-forward direction. However, in most cases, a large range …

Numerical optimization has been ubiquitous in antenna design for over a decade or so. It is
indispensable in handling of multiple geometry/material parameters, performance goals …

A dual-band and dual-polarized leaky-wave antenna excited by slotted substrate integrated
waveguide (SIW) is proposed in this letter. Periodic transverse slots are etched on the top …

In this letter, a dual-beam leaky-wave antenna (LWA) based on dual-mode longitudinal
asymmetry (LA) spoof surface plasmon polaritons (SSPP) is presented. The dispersion …
