“…These highpower jamming systems require phase array antennas with broadband characteristics, since the various target RF devices typically operate in multiple frequency bands. In previous studies, efforts have been made to improve the operating frequency bandwidth of antennas by applying various structures, such as a horn antenna integrated with a substrate board [5], [6], spiral antennas based on a hybrid backed-cavity [7], [8], and a microstrip patch antenna with an L-shaped indirect feed [9], [10]. Although these antennas can achieve the broadband characteristics, the element antenna size is too large to extend to an array antenna.…”

This paper proposes an all-metal Vivaldi array antenna with a wide-angle impedance matching (WAIM) layer for high-power jamming systems. To reduce fabrication complexity and time, the proposed array antenna is manufactured using a metal 3D printing method. The Vivaldi unit cell, composed of a radiating flare part and an inner cavity, is extended into an 8 × 8 array with a ±45° slant configuration. To further enhance the beam steering angle, the WAIM layer is placed on top of the proposed array antenna. The performances of the proposed array antenna, such as its active reflection coefficients (ARC), gains, and array radiation patterns, are investigated in a full anechoic chamber. At a steering angle of (0 = 45°, 0 = 25°), the measured and simulated average ARCs of the center element (Port 36) with the WAIM layer are -13.2 dB and -18.5 dB, respectively. At 4 GHz, the measured and simulated bore-sight gains of the proposed array antenna are 19 dBi and 20.6 dBi, respectively. In addition, the measured and simulated bore-sight gains for the (0 = 45°, 0 = 0°) steering angle in the zx-plane are 18 dBi and 21 dBi, respectively. In the zy-plane, bore-sight gains for the (0 = 45°, 0 = 0°) steering angle are 19.3 dBi by measurement and 19.1 dBi by simulation. These results demonstrate that the proposed array antenna is suitable for highpower jamming systems because stable bore-sight gains are observed even at wide steering angles without unwanted grating lobes.INDEX TERMS High-power jamming systems, 3D printing, all-metal Vivaldi array, unit cell array, wide angle impedance matching

In this paper, we propose a high-durability X-band patch antenna with a coplanar waveguide (CPW) feeding network that can directly connect the upper antenna and the lower transmitting receiver modules without additional cabling. To improve the durability of the antenna, both the sub miniature push-on (SMP) connector and the feed-pin are separated through the CPW layer. This separated structure can minimize the deterioration of the antenna performance when the unwanted movement of the SMP connector occurs from external shocks. To verify the design feasibility, the reflection coefficient and radiation patterns of the proposed antenna are measured in a full anechoic chamber. The reflection coefficient of the proposed antenna is −27 dB at 10 GHz, and the operating frequency bandwidth (|Γ| < −10 dB) is 4.7% (9.82~10.29 GHz) in X-band. The proposed antenna has a maximum gain of 5.7 dBi at the bore-sight direction. In addition, the durability evaluations of the proposed design according to unwanted SMP connector movements provoked by external shocks are investigated using Monte Carlo simulations. The results demonstrate that the proposed high-durability antenna design is suitable for military ship applications that involve exposure to various external shocks.

“…Circularly polarized (CP) patch antennas are widely used in wireless and satellite communications because of their better mobility and weather penetration capacities. [1][2][3][4][5][6][7][8] Achieve to impedance and axial-ratio (AR) bandwidths of the CP patch antennas are the main limitations. As usual, the admissible 3 dB AR bandwidth is commonly small than 10% for the single-feed states.…”

A new wideband microstrip antenna, based on the falcate-shaped patch, with reconfigurable capability at circular-polarization is presented in this article. To achieve both properties of stable radiation characteristics and impedance matching across a broad bandwidth, the combination of the L-probe feeding and falcate-shaped patch is used. An RF-switch is utilized to excite the L-probes and generate either left-hand circular polarization or right-hand circular polarization over the wide operating bandwidth. A prototype of the proposed antenna is fabricated. An excellent agreement exists between the simulation and measurement results. The results reveal a wide impedance matching (|S 11 | < − 10 dB), bandwidth of 55% (1.42-2.5 GHz), and a 3 dB axial ratio bandwidth of 44% (1.6-2.5 GHz). Furthermore, results confirm good radiation and impedance matching performance of the fabricated antenna over the wide bandwidth in comparison with previous related investigations. The reported reconfigurable antenna can be used as a suitable choice for GPS, ISM band, or RFID applications
