A compact dual wideband semi‐circular shape micro‐strip patch antenna is proposed for Ku/K band applications. The proposed antenna structure comprises of a modified T‐shape slot on the patch. Simulated and measured bandwidths of 2.12 GHz and 1.92 GHz at lower frequency bands (16.60‐18.72 GHz) and (16.78‐18.70 GHz) respectively are reported. We observe simulated and measured bandwidths of 0.77 GHz and 0.81 GHz at higher frequency bands (22.66‐23.43 GHz) and (22.56‐23.37 GHz), respectively. Ringing resonating frequencies are observed at lower operating band and are responsible for gain degradation.

“…A probe feeding dual-resonance patch antenna is analyzed in [9]. Another work uses same dielectric thickness and designs presents a high gain multiple resonance patch antenna in the Ku-band [10]. A probe-fed triangular shaped patch antenna, which uses symmetric slots, is presented in [11], where a parametric study similar to our work is conducted.…”

This paper presents a high-gain, dual resonance microstrip patch antenna which operates at 4.285 GHz and 4.425 GHz. Measurement results show an input match of -21.2 dB and electric field phi-polarized gain is 8.52 dB. Cross-polarization levels are better than 30 dB. A slotted geometry was used in order to manage resonance frequencies effectively. 3-D simulations, a parametric study and implemention details are presented. The antenna geometry is very simple with three rectangular slots thereby achieving easy fabrication performance over previously published similar works in literature.

“…It can be observed from Figure 5 that the dimensions of the antenna are 16 mm (dx) × 18 mm (dy) and the antennas are combined with a well-known 100 Ω T-junction structure (fw1 = 1.6 mm, fw2 = 0.6 mm). The feeds of each antenna element have constant amplitude and the same phase [6,7] and Taconic-TSM substrate is used (h = 0.76 mm) for the combiner circuit.…”

Design and realization of a novel planar array antenna and low power LNA for Ku-band small satellite communications

et al. 2017

This article presents both a four-element novel microstrip array antenna and a low noise amplifier (LNA) for a Ku-band small satellite receiver. It includes all design details with measurement results of the fabricated array antenna and LNA. Measured minimum and maximum gains of the proposed antenna are 10.1 and 10.9 dBi in 11.9-12.9GHz band frequency. The designed LNA has a noise figure lower than 1.5 dB and gain higher than 8 dB (at 2 V, 10 mA biasing). In order to reduce the design period and cost, discrete components are chosen and a hetero-junction FET is used as the active component because of better Ku band performance and stability. The simulation and fabricated measurement outcomes of the array antenna and LNA show competent and qualified matching that can be practically used together.
