Abstract
A compact triple band antenna by using etching slots technique in the radiation element is presented in this paper. The proposed antenna is designed to target three different frequencies: 7.5 GHz (military satellite communication), 9 GHz (radar applications) and 28 GHz (fifth generation applications). The fabricated prototype of the antenna has overall dimensions of 13x12.8x1.6 mm3. Measurements were carried out to validate the simulation results. The impedance bandwidths are 259 MHz (7.435-7.695 MHz), 355 MHz (8.86-9.221 MHz) and 2.67 GHz (26.79-29.433 GHz) with return loss less than -10 dB. Furthermore, the suggested antenna provides a gain of 3.96 dBi, 3.05 dBi and 5.86 dBi at 7.5 GHz, 9 GHz and 28 GHz respectively. Therefore, the results demonstrate that the proposed triple band antenna can be used for military satellite communication, radar applications and is a good candidate for the future 5G applications.
Highlights
Arapid technological development in the field of telecommunications, including wireless communication systems, mobile phones, satellites, radar applications, etc. is noticeable
The fifth generation, known as IMT-2020, will use the millimeter wave frequency band, the 28 GHz frequency band because propagation losses at 28 GHz are not significant compared to other frequencies in the millimeter wave band [3, 4]
The diversity of applications involves the integration of many antennas and the use of several bands. These challenges have led to a great focus on multi-band antennas that allow simultaneous coverage of different bands
Summary
Arapid technological development in the field of telecommunications, including wireless communication systems, mobile phones, satellites, radar applications (civil, military, aeronautics, maritime and meteorology...), etc. is noticeable. Arapid technological development in the field of telecommunications, including wireless communication systems, mobile phones, satellites, radar applications (civil, military, aeronautics, maritime and meteorology...), etc. Wireless communication systems has developed enormously from the first generation. IMT-2020, will use the millimeter wave frequency band, the 28 GHz frequency band because propagation losses at 28 GHz are not significant compared to other frequencies in the millimeter wave band [3, 4]. The essential point of the 5G is that it will respond to a large number of completely new challenges in industrial automation (industry 4.0). The diversity of applications involves the integration of many antennas and the use of several bands. These challenges have led to a great focus on multi-band antennas that allow simultaneous coverage of different bands. The main goal of our work is the conception of a multiband antenna that has a high performance and small in size
