This article provides a comprehensive review of recent applications of characteristic mode
analysis (CMA) to innovative antenna element designs, including multiport, circularly …

Characteristic modes can be used to solve many radiation and scattering problems involving
fully conducting structures. The basic concept is to use eigenvalues and eigenvectors of the …

Resonant metasurface (MTS) antennas (RMAs) are antennas leveraging unusual standing-
wave modes of truncated MTS. By introducing resonant exciters, such as wire (electric …

In this paper, an angular symmetric, common radiator coplanar waveguide (CPW) fed four-
port multiple-input-multiple-output (MIMO) antenna is designed on a RT Duroid (, tan) …

A low-profile broadband dual-circularly-polarized metasurface antenna is proposed. The
antenna consists of a modified cross-slot coupling antenna with a lattice of 4× 4 square …

This letter proposes a low-profile circularly polarized metasurface antenna with a wide axial-
ratio beamwidth (ARBW). The proposed antenna consists of an array of square metallic …

A metasurface (MS) based on loop elements operating in the near field of a linearly-
polarized microstrip antenna is employed to realize a circularly polarized radiated field. The …

In this work, we propose a low-profile single-layer coplanar waveguide (CPW)-fed
metasurface (MTS) antenna with broadband circular polarization (CP) radiation. With the …

In this letter, a low-profile wideband pattern diversity antenna based on metasurface (MTS)
is proposed. Initially, based on the theory of characteristic mode (TCM), the two adjacent …

A wearable textile multiband antenna with full ground plane for wireless body area network
(WBAN) applications is presented in this article. The bandwidth enhancement techniques of …
