Dual-Band Annular-Ring Microstrip Patch Antenna for Satellite Applications
A dual-band circularly polarized antenna fed by four apertures that covers the bands of GPS, Galileo, is introduced. The ARSAs designed using FR4 substrates in the L and S bands have 3-dB axial-ratio bandwidths (ARBWs) of as large as 37% and 52%, respectively, whereas the one using an RT5880 substrate in the L band, 61%. In these 3-dB axial-ratio bands, impedance matching with VSWR<=1.8 is also...
متن کاملCircular Ring Loaded Monopole Dual Band Patch Antenna
Abstract— Miniaturized structure and multiple band performance of a patch antenna are primary requirements for modern wireless communication systems. In this paper, a novel design of monopole dual band microstrip patch antenna with circular ring has been proposed for S and C band applications. For dual bands (4.0 GHz and 4.68 GHz), proposed patch antenna shows quite satisfactory radiation perfo...
متن کاملCompact Notch Loaded Microstrip Patch Antenna for Wide Band Application
In this paper, compact notch loaded microstrip antenna is analyzed using Zeland IE3D simulator and circuit theory concept. Analysis on varying thickness, dielectric constant, length and width of the notch has been reported. The bandwidth obtained by the proposed antenna is about 41.8%. Key WordsWide band, Microstrip Patch Antenna, Return Loss, Dielectric Substrate.
متن کاملRectangular Ring Microstrip Patch Antenna for Ultra-wide Band Applications
ABSTRACT: The printed antenna is one of the best antenna structures, due to its low cost and compact design. In this paper, we present a new approach to improve the radiation effectiveness and the performance of antennas by miniaturization of the size. Indeed, we have studied the performance of ultra wideband antenna which consists of a ring-shaped patch. This study was made for the whole frequ...
متن کاملDual Band T Slot Rectangular Microstrip Patch Antenna
Microstrip patch antennas are light weight and low profile antennas so use of these kind of antennas are more easy in portable and small communication devices where size is concerned . In this paper the analysis of T –slot rectangular microstrip patch antenna is presented. The antenna is designed for wide applications in C-band space communication and wireless LAN communication systems. The ban...
