    • Cylindrical dielectric resonator antenna-based sensors for liquid chemical detection 

      Iqbal, Amajad; Smida, Amor; Saraereh, Omar A.; Alsafasfeh, Qais H.; Khaddaj Mallat, Nazih Khaddaj; Lee, Byung Moo (MDPI AG., 2019)
      A compact, cylindrical dielectric resonator antenna (CDRA), using radio frequency signals to identify different liquids is proposed in this paper. The proposed CDRA sensor is excited by a rectangular slot through a 3-mm-wide ...

    • Design of Wideband Circular-Slot Antenna for Harvesting RF Energy 

      Muhammad, Surajo; Smida, Amor; Waly, Mohamed Ibrahim; Mallat, Nazih Khaddaj; Iqbal, Amjad; Khan, Sadeque Reza; Alibakhshikenari, Mohammad (Hindawi Limited, 2022)
      The design of a wideband circular-slot antenna for RF signal harvesting is reported in this work. The proposed design frequency range accommodates the leading contributors to the available RF signals accessible by the RFEH ...

    • Dielectric resonator antenna with reconfigurable polarization states 

      Iqbal, Amjad; Waly, Mohamed I.; Smida, Amor; Mallat, Nazih K. (John Wiley and Sons Inc., 2020)
      This study presents a simple and low-profile cylindrical dielectric resonator antenna (CDRA) for the fifth-generation (5G) band (3.5 GHz) with switchable polarization. The antenna can operate with linear or circular ...

    • Frequency and pattern reconfigurable antenna for emerging wireless communication systems 

      Iqbal, Amjad; Smida, Amor; Khaddaj Mallat, Nazih Khaddaj; Ghayoula, Ridha; Elfergani, Issa; Rodriguez, Jonathan; Kim, Sunghwan (MDPI AG., 2019)
      A printed and minimal size antenna having the functionality of frequency shifting as well as pattern reconfigurability is presented in this work. The antenna proposed in this work consists of three switches. Switch 1 is a ...

    • Low-profile frequency reconfigurable antenna for heterogeneous wireless systems 

      Iqbal, Amjad; Smida, Amor; Abdulrazak, Lway Faisal; Saraereh, Omar A.; Mallat, Nazih Khaddaj; Elfergani, Issa; Kim, Sunghwan (MDPI AG., 2019)
      A low-profile (0.21λg× 0.35λg× 0.02λg ) and a simply-structured frequency-switchable antenna with eight frequency choices is presented in this paper. The radiating structure (monopole) is printed on a 1.6-mm thicker, ...

    • SIW-based frequency-adjustable antenna for IoT-based duplex wireless devices 

      Iqbal, Amjad; Al-Hasan, Muath; Mabrouk, Ismail Ben; Andreasson, Pererik; Nilsson, Emil; Smida, Amor; Denidni, Tayeb A. (Elsevier GmbH, 2024)
      This paper proposes a compact and frequency-adjustable/reconfigurable dielectric (DR)-loaded eighth-mode substrate integrated waveguide (EMSIW) antenna for duplex wireless communications. The miniaturization of the resonators ...
