“…Because of its low price, small size, simple manufacturing, easy installation, and convenience of use, the microstrip antenna is the most often used antenna in communication systems 3,4 . However, it has a low gain, a narrow bandwidth, low efficiency, and a low power handling capability 5 . The greatest interest in the sub‐6 GHz spectrum is in the 3.5 GHz band, which has a bandwidth of 3.4–3.8 GHz, is widely commercially available, and can be used with the hardware of the current communication systems with just small modifications 6 .…”

SummaryIn this paper, an equivalent circuit model‐based electrically small patch antenna is designed for sub‐6 GHz 5G application (3.5 GHz) using 50‐Ω microstrip line feed. The overall size of the proposed antenna is 0.33λ0 × 0.4λ0 × 0.019λ0 (28 × 34 × 1.6 mm3) at 3.50 GHz frequency. The proposed antenna has a tilted Y‐shape slot, two rectangular shape slots, and two rectangular shape notches in the radiating patch. The proposed antenna is resonating from 3.21 to 3.74 GHz covering the entire sub‐6 GHz 5G band (3.3–3.8 GHz). The impedance bandwidth (simulated) of the proposed antenna has been obtained 530 MHz resonating at 3.50 GHz frequency. The good return loss of −23.62 dB is also obtained at 3.50 GHz resonant frequency. The simulation results and geometry of the proposed antenna are validated with equivalent circuit model and experimental measurement of prototype antenna using vector network analyzer (VNA) and anechoic chamber. In the whole operating frequency range, the measured findings show reasonable agreement with the simulated ones. The measured impedance bandwidth of the proposed antenna has been obtained 480 MHz (3.21–3.69 GHz) resonating at 3.48 GHz frequency with a return loss of −21.61 dB, while the theoretical impedance bandwidth of the proposed antenna has been obtained 720 MHz (3.18–3.90 GHz) resonating at 3.58 GHz frequency with a return loss of −21.5 dB. The peak gain of 3.39 (simulated) and 3.2 dB (measured) is obtained at 3.50 GHz frequency. Moreover, the antenna shows 97% (simulated) and 95% (measured) efficiency at 3.50 GHz frequency.

“…All antennas, no matter what their design, have inherent performance constraints based on their geometry [1]. Generally, fewer constraints result in a larger design space which can be exploited to realize antennas with unintuitive and complex geometries that have desirable properties such as wide bandwidth, high gain, strong circular polarization, and compact size [2,3,4]. However, some level of constraints are needed as completely unrestricted antennas may not be fabricable with traditional methods such as CNC machining.…”

A Shape Generation Method for 3D Printed Antennas With Unintuitive Geometries

et al. 2022

Additive manufacturing used in combination with versatile shape generation methods can enable designers to realize unintuitive antenna designs with bespoke electromagnetic behaviors that would normally be extremely difficult or even impossible to manufacture using conventional techniques. In this paper, we present a new custom algorithm that produces arbitrary three-dimensional (3D) meander line antennas. This algorithm is used in conjunction with multi-objective optimization to create two quadrifilar helix antennas (QHAs) and one monopole antenna, all with unique electromagnetic performances. One QHA has a wide bandwidth, high broadside gain, and compact size, while the other has a dual-band nature with different radiation patterns in each band. Similarly, the monopole example is a dual-wideband design which targets Wi-Fi applications. These structures possess a meander radius that varies with height as well as conductor thickness that varies along the meander path which allows for improved antenna performance over conventional meander line antennas. An example design was fabricated and tested in order to validate the performance of the optimized virtual antenna model.

“…They are evolving with independent shapes of numerous designs by the modern-day researchers with respect to their usability and requirement. Different methods are used to design a MPA, among which DGS is one of the popular strategies to enhance the radiation characteristics of the MPA [ 11 ]. DGS is a very popular technique for its versatility and independence of structure [ 12 ].…”
