“…A stepped design was also used to enhance the bandwidth and the aperture of the antenna contains a dielectric to decrease the coupling loss of antennas. Their results show that the antenna has a 60% increase in efficiency and a gain of more than 23.1 sidelobes [14]. Their study showed how dielectrics can be used to reduce the coupling loss.…”

Antennas are useful devices as they are used to enable long distances communications. Up until today, there are still researches about designing an to further progress and innovate the said device. There are many ways in improving the antenna such as varying the size and many more. In this research, the students will demonstrate how the substrate and shape of an antenna cavity influence the performance of a dipole antenna. The substrate is an important part of designing antennas as there is no ideal substrate, and different substrates have different applications. In addition to that, the substrate affects the electrical performance of the antenna and its amplifier circuit. For the antenna substrates, the students will use 9 different substrates. For the shapes, the students will use rectangular and circular shapes. Therefore, in the end, the students will test and gather results to determine which of the substrates is the best among them, and which shape of the antenna cavity is better than the other.

A novel wide 3-dB axial ratio (AR) circularly polarized 2 × 2 array antenna is proposed in this paper. The spindle-shaped coupling cavity with tilted waveguide is capable of generating circular polarization waves from incident linear waves, which improves the AR bandwidth (ARBW) of the antenna. With this structure, a similar amplitude of the two orthogonal transmitted wave components and a stable phase difference of nearly 90° can be generated. The circularly polarized antenna proposed herein has been fabricated. According to the measurement results, the operating bandwidth from 5.32 to 6.13 GHz is <−10 dB. In addition, the measured ARBW, which is below 3 dB, can cover the range of 5.41–6.02 GHz. The maximum gain of the antenna can attain 15.65 dBi, and the efficiency is better than 80%.

“…A common way to design a 45° linearly polarized antenna is to rotate the radiating slots by 45° [15]- [17]. To avoid grating lobes, the period between adjacent radiating elements is usually smaller than one free-space wavelength corresponding to the highest operating frequency in the bandwidth [18]- [22]. In such confined space, it is difficult to implement a full corporate-feed network that excites the radiating slots in a one-to-one correspondence.…”
