    ABSTRACT: A novel design of corporate fed four element rectangular microstrip array antenna (FRMAA) has been proposed for triple band operation at X-band frequency. By increasing the number of array elements from four to eight, the triple band operation can be converted into dual bands. This overall impedance bandwidth is 1.16 times more than the impedance bandwidth of FRMAA with improved broadside radiation characteristics. The dual-frequency patch antennas may provide an alternative to large-bandwidth planar antennas, in applications in which large bandwidth is really needed for operating at two separate transmit-receiver bands. When the two operating frequencies are far apart, a dual-frequency patch structure can be conceived to avoid the use of separate antennas. The design concept of antennas is presented and experimental results are discussed.

    ABSTRACT: This article presents a novel design of corporate fed four-element equilateral triangular microstrip array antenna (FETMSA) for multiband operation, which is attractive for emerging wireless communication systems. If FETMSA is fed through aperture, the coupling converts its multiband operation into triband operation. Further by using optimum slots in the radiating elements converts its tribands into dual wide bands, which may find application in synthetic aperture radar. The overall magnitude of impedance bandwidth is found to be 23.74% at X-band frequencies with broadside radiation characteristics. This impedance bandwidth is 2.61 times more when compared with the impedance bandwidth of FETMSA. © Wiley Periodicals, Inc.
