A compact dual-coupled shorting probe (DCSP)-loaded patch antenna for dual-band global
positioning system (GPS) application is presented. Due to the use of shorting loaded …

This article proposes a concept of compact planar multipole antenna configured by multiple
magnetic and electric dipoles as a single radiation element with a single signal excitation …

The fundamental working principle of front-to-back ratio (FTBR) enhancement of the
quadruple inverted-F antenna (QIFA) is clearly revealed for the first time, and a unified …

An improved three-dimensional circularly polarized quadrifilar helix antenna (QHA) with low
profile and wide 3-dB beamwidth is proposed and its performance is investigated both …

We have proved in theory and simulation that the circularly polarized (CP) radiation from a
resonant quadrifilar helix antenna (QHA) is independent of the phase between two …

In this paper, we propose a novel electrically small dual-band reconfigurable antenna. By
using a compact eighth-mode substrate integrated waveguide (EMSIW) structure, we …

A low-profile and meandered crossed dipole antenna design for ultrahigh-frequency (UHF)
radio-frequency identification (RFID) circularly polarized (CP) tag or handheld reader …

A miniature coupled double loop (CDL) antenna for dual-band GPS application is
presented. The antenna layout employs lumped capacitors and inductive pins over a …

In this communication, a compact dual-band quadruple inverted-F/L antenna (QIFLA), with
right-hand circular polarization (RHCP) for global positioning system (GPS) L1/L2 band, is …

In this letter, we propose a novel feed network for circular polarization (CP) diversity
antennas to enhance communications performances. The previous CP diversity systems …
