Abstract: A monopole broken heart shaped antenna is presented in this article. The WiMAX band application has been taken as objective. The proposed antenna design is carried out in different iterations to obtain the required band. Proposed broken hearts shaped antenna works in the band from 3.2GHz – 4.1GHz.the heart shaped double slotted ring resonator (SRR) with two different radius is seen in the final iteration to enhance the bandwidth (900MHz), and gain (3dB). The other parameters such as VSWR (almost < 2 at WiMAX band), impedance (both real & imaginary), efficiency which is almost 89%has been noticed in this design. So, the proposed broken heart shaped monopole antenna which works at WiMAX band shows the moderate gain, size reduction omnidirectional pattern, high efficiency, etc. which are important in WIMAX application band.
