This paper presents a new approach to implement planar shared-aperture dual-band dual-
circular polarization (CP) array antennas. The antennas can be fabricated on a single-layer …

A novel single-layer single-probe-feed asymmetrical fractal boundary microstrip antenna is
considered for triband circular polarization (CP) operation. Four different structures-without …

A compact single-feed circularly-polarized (CP) wide beam microstrip antenna is proposed
for CNSS application. The antenna is designed with a double-layer structure, comprising a …

A triband circularly polarized (CP) crossed-dipole antenna is introduced for 2.4/5.2/5.8-GHz
wireless local area network (WLAN) applications. It employs a single feed and only two …

This letter discusses the development of a dual-band omnidirectional circularly polarized
(CP) antenna using the zeroth-and the first-order resonance modes of epsilon-negative …

A dual-band circularly polarized antenna for GPS L1 and L2 bands is proposed and
investigated in this letter. The dual-band design is realized based on the strategy of …

An omnidirectional dual-band dual circularly polarized (CP) antenna with wide beam
radiation patterns using TM 01 and TM 02 modes is investigated. The proposed antenna is …

A practical technique for creating dual-band dual-sense circular polarization is presented in
this letter. On the ground plane, two identical slot radiators are etched out orthogonally and …

A single-feed tri-band circularly polarized (CP) annular slot antenna is presented. The
antenna structure is composed of two non-concentric annular slots that are fed by an L …

This study proposes a single‐layer dual‐broadband circularly polarised (CP) antenna that
operates at 2.4, 5.2 and 5.8 GHz for wireless local area networks (WLAN) applications. An …
