A Microstrip Antenna Array Formed by Microstrip Line Fed Tooth-Like-Slot Patches

Analysis of Microstrip Line Fed Patch Antenna for Wireless Communications

“…These antennas have been successfully utilized in many communication systems [1][2][3] such as satellite communication/ links (vehicular GPS), cellular communication system (GSM/CDMA), wireless personal area (Bluetooth links), wireless local area network (Wi-Fi) and synthetic aperture radar (SAR). There are different techniques by which these antennas can be designed for various wireless applications such as proximity coupling [4], aperture coupling [5,6], loading of notches [7], slots [8][9][10], parasitic elements [11], L-strip fed [12,13], microstrip line feeding [14][15][16][17][18][19]. One of the important techniques is inset feeding by which patch antenna can be excited to achieve dual-band and multi-band frequencies for wireless communications.…”

“…The various contributions of researchers and scientists on microstrip line feeding are reported such as, analysis and design of annular patch antenna with electromagnetically coupled microstrip feed line [14], crescentshaped multiband planar monopole antenna for mobile wireless applications [15], microstrip antenna array formed by microstrip line fed tooth-like-slot patches [16], printed wide-slot antenna with a modified L-shaped microstrip line for wideband applications [17], microstrip line-fed printed wide-slot antenna with a parasitic center patch [18], broadband T-shaped microstrip-fed U-slot coupled patch antenna [19]. All the above reported papers are of microstrip line fed patch antennas which lack theoretical analysis, equivalent circuit diagram and has complicated antenna geometry.…”

“…Microstrip antennas [1] are the most rapidly developing field in the last twenty years. Currently these antennas have a large application in mobile radio systems, integrated antennas, satellite navigation receivers, satellite communications, direct broadcast radio and television, etc.…”

An Uwb Microstrip Antenna Array With Novel Corporate-Fed Structure

“…Now there are two kinds of microstrip antenna arrays according to the feed network, namely series-fed array and corporate-fed array [1,2]. The series-fed array [3], formed by interconnecting the radiation elements with high-impedance microstrip line, is simple and has compact feed network, but is subject to beam squint with frequency, so it cannot be used in UWB antenna array design. As to the corporate-fed array [4][5][6][7][8], the elements are fed by a power divider with identical path lengths from the feed point to each element, which insures phase coherence and broadside array beam, but it experiences efficiency limitation especially in large arrays, where the feed lines are long and complicated.…”
