In this paper, a novel embedded dual-element rectangular dielectric resonator antenna (RDRA) combining Sierpinski and Minkowski fractals is proposed to reduce the size and for wideband applications. To enhance the impedance bandwidth, a DR1 with dielectric material Rogers RT6010 $\varepsilon _{r1}= 10.2$ is embedded concentrically inside the DR2. DR2 is a rectangular ring with dielectric material...
In this paper a novel circular patch loaded Koch snowflake fractal DRA is presented. The use Koch snowflake fractal increases the impedance bandwidth by increases the surface area to volume ratio. The circular patch tunes the resonant frequency towards lower frequency. The Proposed antenna offers a bandwidth of 57.5% (2.61GHz–4.72GHz) for reflection coefficient S11<−10dB. The antenna has a peak...
A compact wideband Triangular Dielectric Resonator Antenna (TDRA) is analyzed and simulated. Perforations improve bandwidth by letting down the quality factor. The perforations are array of symmetrical circular-shaped slots drilled uniformly on the TDRA. On proposed the optimal size of slots and distance between two consecutive slots, the fundamental modes of the TDRA is preserved. This aids in making...
In this paper, a novel Minkowski Half-hexagon Notched Dielectric Resonator Antenna (MHNDRA) is proposed to increase the surface to volume ratio, bandwidth and operate at high-order modes to achieve enhanced gain. The material selected for the Dielectric Resonator(DR) is Rogers RO3006,which has a dielectric constant of 6.15 and exited by a coaxial probe. The proposed antenna offers a wide impedance...
