The realization and validation of a new reconfigurable metasurface high‐resolution steering reflector for K‐band are presented. The continuous tuning is achieved by integrating a varactor diode with each metasurface unit cell. This approach is shown in many studies, but not above Ku‐band, because of implementation difficulties. This letter presents design considerations, reflection simulations, and reflection measurements of a new resonant unit cell at K‐band, used for reconfigurable metasurface steering reflector. The reflection steering method and the reflection phase calibration are presented. Finally, the experimental far‐field results are provided to validate the continuous beam‐steering reflector performances in various frequencies at K‐band, with large‐angle steering, high resolution, and wide‐incident‐angular‐range abilities.

“…On the other hand, full integration entails designing an integrated antenna that doesn't need either the 50 Ω interface impedance nor any increase in size to the base antenna. In [16]- [21], a number of novel instances of fully integrated filtering antennas have been reported. These include the incorporation of narrow band-pass resonator on Vivaldi antenna [22], radiation null on a narrow band substrate integrated waveguide slot antenna [23] and on the metasurface antenna [24], the implementation of a notched-band on wideband Vivaldi antenna [25], and harmonic suppression on narrowband patch antenna [26].…”

This paper introduces a novel filtering approach that employs integrated periodic structures with a conventional Vivaldi antenna to achieve a fully integrated bandpass filtering antenna. The approach results in a wide out-of-band suppression, high passband selectivity, adjustable operational bandwidth, and low insertion loss. The proposed filtering approach maintains the original size of the conventional Vivaldi antenna (base antenna) without requiring additional modifications. To validate the approach, we present two filtering Vivaldi antennas: filtering antenna I (center frequency: 18GHz, fractional bandwidth: 21%, insertion loss: 0.32dB) and filtering antenna II (center frequency: 6.5GHz, fractional bandwidth: 12%, insertion loss: 0.6dB). Their wide out-of-band gain suppression (typically ≥15dB) covers the conventional Vivaldi antenna's frequency range (4-24GHz). A prototype of the filtering antenna I is manufactured. Its measurement results validate the proposed approach and show good agreement with the simulated reflection coefficient, realized gain, and radiation patterns. The features of the proposed filtering antenna approach, make it suitable for various applications requiring efficient frequency filtering.INDEX TERMS Filtering antenna, fully integrated antenna design, metasurface, out-of-band suppression, wideband antenna, filtenna.

“…Te impact of removing the ground plane partially over the radiation characteristics of the carpet fractal antenna is investigated in [14]. A short-ended metamaterial structure coplanar waveguide (CPW) fed compact antenna using U-shaped and rectangular shaped strip is designed for a maximum radiation efciency is presented in [15]. Square CSRR structure is introduced in the ground plane of a rectangular patch for size reduction in industrial, scientifc, and medical (ISM) band applications [16,17].…”

This paper presents the implementation of a triple band microstrip patch antenna based on modified split ring resonator (SRR) and modified complementary split ring resonator (CSRR) as defected ground plane. The antenna is designed in a FR4 substrate of dielectric constant 4.4 with dimensions as 35 mm × 35 mm × 1.6 mm that comprises a total designed antenna volume of 1960 mm3. Multiband operation is introduced in the antenna through multiple resonators that are introduced in the patch. Impedance matching was provided with the help of partial ground plane and modified SRR in patch. The simulation performance of the antenna is verified using high frequency structural simulator (HFSS) software. The designed antenna resonates at 2.8 GHz, 5.8 GHz, and 6.9 GHz for the application requirements of WiMAX, ISM, and Sub-7 GHz wireless communication. The antenna is fabricated as printed circuit board (PCB) format, and its return loss characteristics are measured using a vector network analyser (VNA). The measurement results of the proposed triband antenna are in good agreement with simulated return loss characteristics.
