    • A compact UWB antenna with independently controllable notch bands 

      Iqbal, Amjad; Smida, A.; Khaddaj Mallat, Nazih Khaddaj; Islam, Mohamad Tariqul; Kim, Sunghwan (MDPI AG., 2019)
      A minimally-sized, triple-notched band ultra-wideband (UWB) antenna, useful for many applications, is designed, analyzed, and experimentally validated in this paper. A modified maple leaf-shaped main radiating element with ...

    • 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 ...

    • 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 ...

    • Six-port interferometer for W-band transceivers Design and characterization 

      Moldovan, Emilia; Khaddaj Mallat, Nazih Khaddaj; Tatu, Serioja Ovidiu (Institute of Advanced Engineering and Science, 2019)
      The study has presented an extensive analysis of an integrated millimeter wave six-port interferometer, operating over a 10 GHz band, from 80 to 90 GHz. It has covered both semi-unlicensed point-to-point links (81-86 GHz), ...

    • Slot-DRA-based independent dual-band hybrid antenna for wearable biomedical devices 

      Iqbal, Amjad; Alazemi, Abdullah J.; Khaddaj Mallat, Nazih Khaddaj (IEEE., 2019)
      A hybrid dual-band antenna, consisting of an L-shaped radiating slot and a cylindrical dielectric resonator antenna (CDRA) is proposed, simulated and experimentally validated in this paper. The microstrip transmission line ...

    • Wideband Circularly Polarized MIMO Antenna for High Data Wearable Biotelemetric Devices 

      Iqbal, Amjad; Smida, A.; Alazemi, Abdullah J.; Waly, Mohamed I.; Khaddaj Mallat, Nazih Khaddaj; Kim, Sunghwan (IEEE., 2020)
      This paper presents a miniaturized circularly polarized multiple-input multiple-output (MIMO) antenna for wearable biotelemetric devices. The proposed MIMO antenna consists of four elements, which are placed orthogonally ...
