A Dual-Band and Quadruple-Mode Circular Stacked Patch Antenna With Dual TM<sub>11</sub> and TM<sub>12</sub> Modes
This paper presents a novel wideband dual-band and quadruple-mode circular stacked patch antenna. The dual-band of the antenna comprises a low-frequency TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> mode and a high-frequency TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</inf> mode, with both bands exhibited by dual resonant modes. A slot is opened in the upper patch at the position radiated by the TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> mode, aiming to enable the TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> mode to radiate from the gap. Fed directly through a coaxial line, the symmetric structure of the stacked antenna allows the antenna to generate two resonant points in both resonator bands. The gap in the upper patch excites both modes simultaneously Simulated results indicate that the antenna exhibits a TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> mode impedance bandwidth of 18.6% from 4.72 GHz to 5.69 GHz and a TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</inf> mode impedance bandwidth of 11.8% from 6.38 GHz to 7.18 GHz.
