چکیده
This communication develops a triple-band shared-aperture antenna operating at X/K/Ka-band with high figures of merit such as aperture reuse efficiency and simple configuration to achieve gain. The proposed is implemented by integrating Fabry–Perot (FP) cavity X-band into dual-band reflectarray enabled frequency selective surfaces (FSSs). unit cells (UCs) form the phase-shifting for can offer partial reflectance/transmission abilities simultaneously, thereby enabling implementation an FP antenna. responses are highly independent X/K/Ka-band, which facilitates design optimization. For demonstration, prototype has been described, fabricated, measured. simulated results present 3 dB gain bandwidths 11.2% (8.4–9.4 GHz), 10.0% (24–26.6 13.3% (35–40 all experimentally verified. measured also peak 16.8 dBi 9.0 GHz, 23.8 26 26.7 38 GHz.

Design of a Triple Band-notched UWB Planar Monopole Antenna
In this paper, a novel design of a compact planar ultra wide band (UWB) monopole antenna with triple band notched characteristics has been presented. The antenna has a unique shape and has been fed through a 50 Ω microstrip feedline. The strength of the antenna lies in three band notched properties for WiMax system at 3.3 3.7 GHz, WLAN IEEE 802.11a at 5.15 5.85 GHz and X band satellite communic...
متن کاملDesign and Analysis of Ultra-wide Band Bandpass Filter Using Spiral Stub-Loaded Triple-Mode Resonator with a Notched Band
An ultra-wide band band-pass filter using novel spiral stub-loaded triple-mode resonator (SSLTMR) is presented. New spiral stub loaded resonator is analyzed with odd and even modes analysis for this class of BPF, achieving higher band wide and size reduction. In order to have a good response characterized, two (SSL-TMRs) and two quarter wavelength digital coupled lines are used. This new design...
متن کاملDesign of E-Shaped Triple Band Microstrip Patch Antenna
The paper presents the design of patch antenna that can operate on a triple band 2.4GHz, 4.6GHz, 5.5GHz. The shape of the patch resembles an English alphabet `E`. Two parallel slots are incorporated to get the shape of ‘E’ and the dimensions were optimized using CST Microwave Studio EM Simulator. Different parameters like return loss, VSWR, Radiation pattern in 3D are presented.
متن کاملAperture coupled Wide-Band Micro Strip Antenna Design
Microstrip patch antennas are well suited for integration in to many applications owing to their conformal nature. There are many wide banding techniques used for the MSAs. But many wide banding techniques such as using slots in the patch require an inductive coupled feed (probe feed). But complete planar (2D) processes for manufacturability needs capacitive coupling. Capacitive coupling with c...
متن کاملShared-Aperture Multi-Band Dual-Polarized SAR Microstrip Array Design
Since the 1970s, the remote sensing synthetic aperture radar (SAR) systems have been devel‐ oping increasingly. The SIR-C/X SAR mounted on the American Space Shuttle Endeavour firstly completed the high resolution 3D imaging all over the globe in Feb. 2000 [1]. It employs three dual-polarized sub-arrays operating at L-, Cand X-bands, respectively, as shown in Fig. 1[2]. The multi-band dual-pola...
