Circularly Polarized Square Ring Slot Antenna with Arrow-Shaped Structure

© 2009 ETRI Journal, Volume 31, Number 5, October 2009 A novel design of a compact square-ring slot microstrip antenna for achieving circular polarization (CP) operation is proposed and experimentally studied. By using an arrow-shaped slot structure as a radiating element, the resonant frequency of the proposed antenna is significantly lowered, which can lead to a large size reduction for fixed...

A Wideband Circularly Polarized Slot-Loaded Dipole Antenna with L-Shaped Arms and Parasitic Patches

In this paper, a broadband circularly polarized (CP) antenna based on slot-loaded dipole with L-shaped arms and parasitic patches is proposed and investigated. Circular polarization is initially obtained at the lower frequency by bending the dipole arms into L-shape. To extend the axial ratio (AR) bandwidth, two pairs of parasitic patches are introduced along the orthogonal sections of the L-sh...

Design of Slot Cut Circularly Polarized Rectangular Microstrip Antenna

Circularly polarized slot cut rectangular microstrip antenna on thinner substrate is proposed. The dimensions of the slots are modified such that the resonance frequencies of the two orthogonal modes are close to each other to realize circular polarization. To improve upon the gain, three layer suspended configuration is proposed which yields VSWR and axial ratio BW of 40 and 9 MHz, respectivel...

Circularly Polarized Microstrip Patch Antenna with T - Shaped Slot

In this paper a new geometry of circularly polarized patch antenna is proposed with improved bandwidth. The radiation performance of proposed patch antenna is investigated using IE3D simulation software and its performance is compared with that of conventional circular patch antenna. The simulated return loss, axial ratio and impedance with frequency for the proposed antenna are reported in thi...
