Perforated Dielectric Resonator Antenna Operating on Higher Order Mode
A wideband, high gain perforated dielectric resonator antenna (DRA) is presented in this paper. Higher order TEδ15 mode is excited to enhance the gain, while perforations improve the bandwidth of the proposed antenna by lowering down the quality factor. The perforations are array of symmetrical square shaped slots that are uniformly drilled on the DRA. At 26 GHz, the proposed geometry exhibits a wide impedance bandwidth of 17.33% (24.5–27.8 GHz) and a maximum gain of 9.2 dBi. The simulated radiation efficiency is 94% for the complete bandwidth. ECCOCK HiK TEK material with dielectric constant of 10 is used to form dielectric resonator antenna. The DRA is excited by 50Ω microstrip line with aperture slot. The simulated results have been analyzed and discussed in terms of reflection coefficient, gain, efficiency and radiation patterns. The proposed antenna can be used for Internet of Things (IoT) applications such as Device-to-Device (D2D) Communication.
