چکیده
Abstract The article proposes design investigation and experimental results of a coplanar waveguide (CPW) fed square slot antenna that gives wideband circular polarization. This polarization characteristic is achieved by embedding shape stub to left bottom corner an L-shaped strip the right upper slot. A high impedance bandwidth 87.8 % (3.6–9.0 GHz), wide axial ratio 73.05 (4.2–9.0 GHz) 3-dB beamwidth 90° in entire frequency range interest are with this structure. To improve bandwidth, three slots (two horizontal one vertical) scratched at exterior periphery ground plane. These perturbation assemblies accountable excite orthogonal modes help increase bandwidth. designed displays constant steady radiation patterns complete concern. overall dimension presented compact 0.24? × 0.01?.

Bandwidth Enhancement of Circularly Polarized Square Slot Antenna
Bandwidth enhancement technique of circularly polarized square slot antenna is presented in this paper. A square slot antenna with the components of L-probe separated could achieve an axial ratio (AR) bandwidth of 33.84%. Placing Stubs in the slot by studying the electric field behaviour could enhance the AR bandwidth by around 10%. Creating an L-shaped slot on the ground plane, where the elect...
متن کاملWide-Beamwidth Circularly Polarized Antenna and Its Application in a Sequential-Rotation Array with Enhanced Bandwidth
A wide-beamwidth circularly polarized (CP) asymmetric microstrip antenna is proposed by etching four novel unequal fan-shaped notches at the vertexes of the square radiator. A bandwidth of 1.5% and beamwidth of 156◦ are well achieved for an axial-ratio ≤ 3 dB (3-dB AR) at the central frequency of 1.575GHz. To widen the bandwidth, the asymmetric microstrip antenna is further expanded with the co...
متن کاملCircularly 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...
متن کاملDual-band Circularly Polarized Antenna with Low Wide-angle Axial-ratio for Tri- Band Gps Applications
This paper presents the design of a dual-band microstrip antenna with low wide-angle axial-ratio. The antenna is designed for global positioning satellite operations at 1227MHz (L2), 1575 MHz (L1) and 1176 MHz (L5, available after 2007). This antenna has another advantage of a much wider band in both VSWR and 3 dB axial-ratio compared with single-fed GPS antennas. Details of the design, simulat...
