“…The Yagi-Uda antenna array construction is composed of one active element and three vertically stacked Yagi-Uda directors, operating at the frequency of 2.4 GHz. The main objective involved designing and simulating a new Yagi-Uda antenna model to increase bandwidth and directivity, based on [7]. Li studied theoretically different patch shapes (square, circular, triangle, etc.)…”

“…Among the desirable features in antennas to meet current market needs, the design of antennas with more bandwidth is required [6]. Yagi-Uda stacked antenna presented in [7] provides a directivity mode, and since the three directors operate as monopole antennas, they provide pattern diversity, in which directivity mode and diversity mode can be simultaneously achieved. However, it has limited bandwidth and directivity.…”

“…Knowing that one of the big problems of patch antennas is the limitation of its bandwidth. This work aims to improve the results presented in [7] based on the bandwidth parameter, and that this is within the frequencies in which WiFi technology works. The dual-mode stacked antenna array composed of four layers in vertical configuration is analyzed and designed to maintain the compact design of the antenna.…”

This paper describes the design of a Yagi-Uda stacked antenna array for 2.4 GHz applications. Its structure consists of 4 layers, layer 1 contains the active element, the reflector and the transmission line feed. Layers 2, 3 and 4 have circular patches that function as directors. The implementation of a "D" shaped patch on the active element is inserted, where the simulation results show that the proposed antenna can achieve a bandwidth that is much wider than the traditional circular patch antenna. Also the dimensions of the circular patch directors and their distances are chosen to have the highest directivity. The antenna simulation is performed in Ansoft Designer and Ansys HFSS 15.0 software.

A dual‐mode differentially‐fed patch antenna is proposed with out‐of‐band suppression based on substrate‐integrated suspended line (SISL) platform. Taking advantage of the air cavity in the SISL platform, the antenna is with two resonant modes for enhanced bandwidth. One mode is TM01 of the patch and the other one is the TE102 mode of the air cavity. A radiation null is also introduced by the air cavity at the upper band and result in out‐of‐band suppression. To verify the proposed design, a prototype is fabricated and measured. Measurements agree well with the simulations. In the band of 4.73–4.98 GHz, the reflection coefficients are less than −10 dB, which is for the Sub 6 GHz band for the 5G communication. Besides, the efficiency of the antenna is 80% with the low‐cost substrate of FR4.
