Abstract-An 61-channel digital beamforming transmitter array antenna used in mobile satellite communication is presented in this paper.It can steer 16 beams simultaneously. The interface, architecture and subunits are described in detail. Standard hexagonal array (SHA) and 61-channel RF front ends are designed. Genetic Algorithm is adopted to realize the pattern synthesis with mutiobjective optimization. The signal flow and hardware platform of the digital beamforming network are discussed, which can complete the high speed array signal processing with maximum throughput of 34.16 Gbps. A novel calibration scheme with high feasibility of project implementation is also proposed. The measurements of array antenna match well with simulation result, which validates the rationality and feasibility of the algorithms.

“…The proposed antenna in this paper designed with a compact rectangular slot and a cross like structure at the anterior portion of the feed. While comparing the same type of antennas existing in the literature [16][17][18][19][20], the proposed antenna accounts 66% of size reduction. Though the fractional bandwidth of this antenna is reduced by 18% of the existing antennas, the observed 90% fractional bandwidth of the proposed structure is more than sufficient for any UWB applications.…”

Abstract-Design and analysis of a compact coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna is presented in this paper. The antenna consists of a rectangular slot with cross like structure at the anterior portion of the feed which acts as tuning stub. The CPW feed is designed for 50 Ω impedance. The physical dimension of the proposed antenna is 19 mm (length) × 20 mm (width) × 1.6 mm (thickness), and the electrical size is 0.3λ l (length) × 0.32λ l (width) (f l = 4.8 GHz). The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. An extensive analysis of the proposed antenna in the frequency and time domains is presented. The antenna was fabricated with FR4 substrate and characterized by measuring return loss, radiation pattern (5.5 GHz) and gain. The measured results are appreciably in good agreement with the simulated ones. A better impedance bandwidth is obtained from 4.8 GHz to 12.8 GHz that constitutes a fractional bandwidth of 90% with return loss less than or equal to −10 dB (VSWR ≤ 2). Time domain analysis of the antenna is also performed, which witnessed the linear phase and less distortion. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication that may be built for any wireless UWB device applications.

“…Microstrip patch antennas on a thin dielectric substrate inherently have the disadvantage of narrow impedance bandwidth. To increase the bandwidth of a single layer microstrip patch antenna several configurations have been proposed by researchers such as placing parasitic patches on the same layer with the main patch [1], chip resistor loading [2], E-shaped patch [3], placing a U-slot on the patch [4], planer microstrip fed tap monopole antenna [5], rectangular slot antenna with patch stub [6], Vivaldi antenna [7] and square ring patch with shorting posts [8]. Majority of these works carried out are based on relatively thick substrates.…”

Abstract-A new antenna structure comprising a semicircular microstrip patch alongside a small rectangular shape ground proximity fed by a microstrip line is proposed. On a thin substrate this antenna achieves in the range of 5.8-12.9 GHz an impedance bandwidth of almost 75%. Details of the antenna design, simulation and measured results on the return loss and the E and H -plane radiation pattern of the proposed antenna are presented.
