This paper gives a basic review and a summary of recent developments for leaky-wave antennas (LWAs). An LWA uses a guiding structure that supports wave propagation along the length of the structure, with the wave radiating or “leaking” continuously along the structure. Such antennas may be uniform, quasi-uniform, or periodic.

Review of Recent Advances in the Leaky-Wave Analysis of 2-D Leaky-Wave Antennas
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020Recent developments are reviewed in the area of leaky-wave analysis of two-dimensional (2-D) leaky-wave antennas. Recent results are reviewed in three areas: (1) new beamwidth formulas for 2-D leaky-wave antennas, (2) leakywave analysis of wideband Fabry-Perot cavity antennas, and (3) leaky-wave analysis of 2-D periodic leaky-wave antennas (those that ...

Spiral Leaky-Wave Antennas Based on Modulated Surface Impedance
IEEE Transactions on Antennas and Propagation, 2011 Different kinds of spiral planar circularly polarized (CP) antennas are presented. These antennas are based on an interaction between a cylindrical surface-wave excited by an omnidirectional probe and a inhomogeneous surface impedance with a spiral ...

Millimeter waveguides, such as coplanar lines, microstrip lines and dielectric guides, are open structures where energy leakage is bound to occur. This leakage can occur, for example, when there are discontinuities in the guiding structure, or perhaps when the guide is excited in an inappropriate mode.

2009 IEEE Antennas and Propagation Society International Symposium, 2009
In this paper, a trough leaky-wave antenna is considered that was inspired by the half-width microstrip leaky-wave. The TLW antenna is naturally suitable for flush-mount installation in a metallic body such as an automobile. The radiation characteristics will be investigated in more detail such as the design of the matching cavities and their effect on

Resonance analysis of the leaky-wave antenna
2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014The resonance analysis of the leaky-wave antenna with the microstrip feeding has been presented in this paper. Owing to an open-end structure of the leaky-wave antenna, we analyze the antenna by using the cavity-mode technique. Two conventional leaky-wave antennas with two different lengths, defined by the short and long cases, are shown to examine ...

Amplitude-Modulated Leaky-Wave Antennas
IEEE Transactions on Antennas and Propagation, 2021Borrowing the idea of amplitude modulation from classical communications theory, this article proposes and demonstrates a new concept of amplitude-modulated (AM) leaky-wave antennas. In the proposed concept, the traveling wave in a wave-guiding structure serves as the carrier wave whose amplitude is spatially modulated by a predefined modulating ...

Security in terahertz WLANs with Leaky wave antennas
Proceedings of the 13th ACM Conference on Security and Privacy in Wireless and Mobile Networks, 2020This paper presents the first security study of THz networks with Leaky Wave Antennas (LWAs). We employ a mix of analytical models and over-the-air experiments to explore the unique security properties of LWA links. We show via both models and experiments that the LWA's angle-frequency coupling leads to non-uniform secrecy capacity across sub-channels ...

Leaky wave Antenna for mobile phones
International Meeting on Advanced Technologies in Energy and Electrical Engineering, 2020Millimeter wave (mm-wave) is today’s breakthrough frontier for emerging wireless mobile cellular networks, wireless local and personal area networks, simultaneous energy/data transfer, wearable networks, vehicular communications and radar. Directive antennas emerge as a key component in most of these applications driven by the requirement to meet ...
