Improvement in gain as well as bandwidth of microstrip antenna using reactive impedance surface and Fabry Perot cavity resonator is proposed. Suspended microstrip antenna (MSA) is designed on reactive impedance surface (RIS) backed FR4 substrate. RIS improves bandwidth, gain and efficiency of antenna due to reduced coupling between MSA and ground plane. This MSA backed RIS is placed in a FPC resonator...
In this paper, a novel wide band stacked segment microstrip patch antenna (MPA) with two layered RT/Duroid is proposed. Multi-layered stacked patches are designed with rectangular dimensions, and square slots are entrenched with first patch to excite them. A parametric study of dielectric thickness and stacked center is carried out to enhance the impedance bandwidth of the proposed antenna. The antenna...
An optimized planar antenna for transceiver operating at 1800 MHz (DCS band) is designed and presented. The designed microstrip antenna is used for Digital cellular system operating at the frequency of 1800 MHz with the return loss better than 10 dB.FR4 substrate is used in the design with lesser occupancy of 50*40*3.8mm3. The simulated design of antenna confirms satisfactory output gain and omnidirectional...
An Ultra Wide-Band Monopole Antenna with Hexagonal Patch Structure is designed for several wide-band microwave band applications in the X-band (8–12 GHz), Ku-band (12–18 GHz) of the Radio Frequency Spectrum. The patch is designed using Ring Geometry. The antenna design is optimized using Particle Swarm Optimization (PSO) technique. The proposed antenna finds its application in microwave frequency...
This paper presents double-band stacked patch antenna intended for implementation in satellite navigation systems. Antenna frequency operation band covers GLONASS L1 and L2 frequencies and GPS L1 frequencies. Two antenna variants are described - with a separate feed for each frequency band and with a shared feed. Simulation and experimental results are described.
In this paper a simple structure of Ultra Wideband (UWB) antenna is proposed. The antenna offers excellent performance for UWB system, ranging from 3.7 GHz to 13.8 GHz. The antenna exhibits a 10 dB return loss bandwidth over the entire frequency band. The antenna is designed on FR4 substrate and fed with 50 ohms microstrip line. It is found that the frequency band depends on the width of the partial...
