A dual-band circularly polarized antenna with a lumped element for global positioning
system (GPS) applications is proposed and analyzed in this communication. The proposed …

This paper presents a ultra-high frequency (UHF) antenna for partial discharge (PD)
detection and the antenna sensor can be used near a conducting ground wire. The …

This study uses annular circular rings to create multi-band applications using crescent-
shaped patch antennas. It is designed to be made up of five circular, annular rings nested …

This paper presents the crescent-shaped slot antenna loading of a circular patch that greatly
enhances a 3 dB axial-ratio (AR) bandwidth. A bent feeding line was introduced and …

A high-gain rectangular waveguide-fed aperture antenna that uses a Spidron fractal
structure to produce circular polarization is proposed. The antenna consists of a Spidron …

In this letter, a subarray optimization to improve G/T of an active array antenna is presented.
To optimize G/T, an equation for G/T is derived by calculating the formulas of the gain and …

We present a simple and useful closed-form expression to compute antenna input
impedance and the axial ratio of a circular patch antenna with perturbation segments. The …

The design of a stretchable inverted conical helical antenna (SICHA) applicable to maritime
search and rescue is proposed, and the gain and the reflection coefficient are obtained at a …

This study presents a near-field immunity test (NFIT) method for the fast debugging of
radiated susceptibility of industrial devices. The proposed approach is based on the …

This article proposes the design of a four‐element array antenna for the accurate direction of
arrival (DOA) estimation of Global Positioning System (GPS) interference signals. The …
