The basic geometry of a microstrip patch antenna (MPA) consists of a metallic patch printed
on a grounded substrate. Three commonly used feeding methods are coaxial feed, stripline …

Microstrip patch antennas have become the favorite of antenna designers because of its
versatility and advantages of planar profile, ease of fabrication, compatibility with integrated …

A new numerical stochastic optimization algorithm, inspired from colonizing weeds, is
proposed for Electromagnetic applications. This algorithm, invasive weed optimization …

A wide operating bandwidth for a single-layer coaxially fed rectangular microstrip patch
antenna can be obtained by cutting a U-shaped slot on the patch. This antenna structure has …

A single-layer microstrip-fed patch antenna with capabilities of both bandwidth
enhancement and harmonic suppression is proposed. For this purpose, a pair of λ/4 …

is presented. The transmitarray element consists of an active side, a 360° reflective phase …

In this paper, a method to reduce the inevitable mutual coupling between antennas in an
extremely closely spaced two-element MIMO antenna array is proposed. A suspended meta …

In this paper, a ε-negative metasurface superstrate is proposed for mutual coupling
reduction of large antenna arrays. Unlike the previous decoupling metasurface works that …
