  • Multifunctional complementary frequency selective surfaces for wireless applications
    Pooja Prakash, Bidisha Dasgupta
    Journal of Electromagnetic Waves and Applications, 2026
    The paper presents the development of multifunctional frequency selective surfaces (M-FSSs) by using multilayer complementary structures and discusses their possible application in C-band wireless communication systems. The fundamental complementary FSS geometry (M-FSS_1) offers reflector–transmitter (R–T) behaviour that ranges from 1 to–10 GHz. The introduction of a corrugated metallic plate to M-FSS_1 (M-FSS_2) changes the characteristics to reflector–absorber (R–A) over a specified frequency range. This improved (M-FSS_2) geometry provides absorptivity at three frequencies that are greater than 85%. The equivalent circuit model (ECM) of the proposed M-FSS structures is also created to extract their lumped parameters. The proposed M-FSSs can be used to enhance antenna gain, reduce mutual coupling, and achieve RCS reduction, offering a compact and low-cost solution for integrated electromagnetic control in modern wireless systems.
  • A Wideband Multimode Hybrid Dielectric Resonator Antenna for MIMO Application in the 6G-FR3 Band
    Pooja Prakash, Bidisha Dasgupta
    IETE Journal of Research, 2026
    The paper presents a cylindrical dielectric resonator antenna with multimode excitation and its extension as a two-element MIMO antenna. The proposed one is developed as a hybrid antenna by placing the dielectric resonator on a U-shaped patch antenna. The excitation and identification of two TM and three hybrid modes are carried out for the proposed hybrid antenna over two distinct bands: 8.9–12.0 GHz (absolute bandwidth: 3.1 GHz; fractional bandwidth: 29.66%) and 12.5–15.6 GHz (absolute bandwidth: 3.1 GHz; fractional bandwidth: 22.06%), achieving a peak gain of 9.3 dBi. A two-element MIMO antenna is developed by placing the hybrid antenna in orthogonal positions, maintaining characteristics such as an isolation (S21) of less than −25 dB, an Envelope Correlation Coefficient (ECC) of less than 0.002, and a Diversity Gain of about 9.98 dB throughout the band. Also, the Channel Capacity Loss (CCL) is less than 0.4 bits/s/Hz at the radiating frequencies and the TARC value is less than 0 dB throughout the entire operating bands. The design can also be elevated to a four-element MIMO antenna. The proposed hybrid antenna is useful for MIMO wireless applications in the 6G-FR3 band.
  • Reconfigurable Dual-Loop Frequency selective Rasorber with Switch-Tunable Functionality
    Pooja Prakash, Marada Shamita, Bidisha Dasgupta
    Conference Proceedings 2025 IEEE Silchar Subsection Conference IEEE Silcon 2025, 2025
    The paper presents a simple configuration of a multifunctional frequency selective rasorber (MF-FSR) that offers both switchable and tunable characteristics over 3-10 GHz spectrum. The design employs two square loop configuration with PIN diode and varactor diode strategically placed on each side to enable mode switching between reflection and absorption modes. The PIN diodes facilitate mode switching by changing the current flow, while varactor diodes allow precise tuning of the notch band frequencies. During the ON state configuration of the PIN diode, it offers reflection, absorption, reflection properties over 3-10 GHz for TE/TM mode, displaying the absorption in the range of 5-8 GHz. For PIN Diode OFF state, it offers reflection, absorption, reflection, absorption/reflection, reflection properties over 3-10 GHz for TE/TM Mode, displaying the absorption at 4.3-5.2 and 5.7-10GHz. Further by changing the reactive component of varactor diode, it is possible to tune the operating frequencies for reflection and absorption bands. Hence, the proposed rasorber structure is switchable as well as tunable and provides angular stability up to 500. This design offers a compact, cost-effective solution for applications requiring dynamic electromagnetic performance, such as stealth technology and wideband antenna systems for the partial S band, full C band and partial X band (3-10 GHz).
  • Multilayer Complementary Frequency Selective Surfaces with Hybrid Functionality
    Pooja Prakash, Bidisha Dasgupta
    2024 IEEE Silchar Subsection Conference Silcon 2024, 2024
    The paper presents multilayer complementary frequency selective surfaces (FSSs) with hybrid functionality. The proposed structure behaves primarily as a transmitter or reflector over 1–10 GHz and also as a partial absorber for limited frequencies. The proposed FSS reflects signal for seven bands around 2.4 GHz, 3.7 GHz, 4.5 GHz, 5 GHz, 5.4 GHz, 6.4 GHz, and 7.5 GHz and it transmits signal for eight bands around 1.8 GHz, 3.1 GHz, 4.1 GHz, 4.8 GHz, 5.1 GHz, 5.9 GHz, 6.9 GHz, and 8.5 GHz. Also, it is observed that at limited frequencies between 3 to 8 GHz, the absorptivity goes above 25%. It also offers angular stability and polarization insensitivity up to 45°. The paper also addresses an application of the proposed FSS to improve the gain of the microstrip patch antenna. However, the proposed multifunctional structure can be used as a possible candidate to improve gain of frequency reconfigurable printed antenna, to reduce antenna radar cross section etc.
  • Dielectric Resonator Loaded U-shaped Printed Hybrid Antenna for Multiband Wireless Applications
    Pooja Prakash, Bidisha Dasgupta
    2022 IEEE Microwaves Antennas and Propagation Conference Mapcon 2022, 2022
    This paper presents a new type of hybrid antenna geometry which can operate over triple bands. It consists of a U-shaped printed antenna and a cylindrical dielectric resonator antenna (CDRA) along with a ground plane which contains T-shaped slot. The proposed antenna operates over frequency ranges 5.75-6.56 GHz, 9.46 -12.7 GHz and 14.29-16.13 GHz and provides peak gain about 7.3 dBi. Different modes of CDRA like HEM11δ, TM01δ-like, HEM12δ and HEM21δare being excited. The proposed antenna can be used as an electromagnetic sensor for C, X and Ku band applications.
  • Compact Electromagnetic Bandgap (EBG) Structure with Defected Ground
    P. Prakash, M. Abegaonkar, L. Kurra, A. Basu, S. Koul
    IETE Journal of Research, 2016
    In this paper, a compact defected ground mushroom electromagnetic bandgap (DG-MEBG) structure is presented. Compactness is achieved by employing a DG in the conventional MEBG. DG-MEBG exhibits a low pass transmission response with a cut-off frequency of 4.2 GHz and wide stop band up to 17 GHz as against a cut-off frequency of 10.4 GHz observed in a conventional MEBG. Thus the proposed DG-MEBG is 60% compact in comparison with a conventional MEBG structure. The measured results show a very good agreement with the simulated ones.
  • Gain enhancement of a CPW-Fed monopole antenna using polarization- insensitive AMC structure
    P. Prakash, M. Abegaonkar, A. Basu, S. Koul
    IEEE Antennas and Wireless Propagation Letters, 2013
    A polarization-insensitive dual-band artificial magnetic conductor (AMC) structure is designed and experimentally verified. It consists of a planar array of annular ring-slot loaded rectangular patches. Details of the proposed structure and origin of the two bands is discussed. Through simulations and measurements, it is shown that the structure is insensitive to polarization of the incident wave. The tuning of the higher AMC band is demonstrated by varying the capacitance of the annular slot through its width variation. The designed AMC is used as a reflector for a wideband monopole patch antenna. It is shown experimentally at the antenna frequencies in the AMC band that the gain of the antenna improves by almost 10 dB and front-to-back ratio is improved by 15 dB.
