Design and analysis of UWB circular ring two element microstrip patch antenna array with notched band for modern wireless applications

ABSTRACT Two element array of circular ring microstrip patch antenna is proposed for modern wireless applications. A circular slot is integrated in the circular patch for providing a notched band at frequency of 4.6 GHz for avoiding the interference with exciting band at frequency of 4.6 GHz. A 50‐Ω...

Description
Summary:ABSTRACT Two element array of circular ring microstrip patch antenna is proposed for modern wireless applications. A circular slot is integrated in the circular patch for providing a notched band at frequency of 4.6 GHz for avoiding the interference with exciting band at frequency of 4.6 GHz. A 50‐Ω microstrip line power divider is used for feeding the both circular ring elements of array. The corners of the power divider are truncated for providing the better impedance matching. Antenna shows an impedance bandwidth of 185.5% ranging from 1.0 GHz to 13.8 GHz. Proposed antenna shows good radiation characteristics with peak gain of the value of around 8 dBi. Single element of same circular ring fed with microstrip line also proposed with semiground plane. The antenna is analyzed with finite element method using HFSS v.14. Proposed structure is fabricated on Fr‐4 Epoxy substrate and measured results are in good agreement with simulated results. © 2015 Wiley Periodicals, Inc.
