    • 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 ...

    • Electromagnetic bandgap backed millimeter-wave MIMO antenna for wearable applications 

      Iqbal, Amjad; Basir, Abdul; Smida, A.; Mallat, Nazih Khaddaj; Elfergani, Issa; Rodriguez, Jonathan; Kim, Sunghwan (IEEE., 2019)
      A millimeter-wave (mm-Wave) multiple input multiple output (MIMO) antenna operating at 24 GHz (ISM band), suitable for wearable applications, is proposed in this paper. The proposed MIMO antenna consists of two elements, ...

    • 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, ...

    • 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 ...
