The antenna is designed, simulated, and tested by using a network analyzer and anechoic chamber. The radiation pattern is stable and it shows that the designed antenna is a directional antenna. Also, the grooves in the feeding network minimize reverse power reflections. Next, the front-to-back ratio is improved significantly which further results in the gain enhancement. These frequency bands cover 28 GHz and 38 GHz bands of 5G communications. The proposed dualband antenna operates from 24.17 GHz to 29.37 GHz and 30.76 GHz to 40.58 GHz. The designed AVA array size is 2.86 × 3.58 × 0.06 λ g 3 (for lower guided frequency). The antenna frequency response is improved by incorporating corrugations which results in the antenna miniaturization. Its efficiency is in the range of 95.93%–97.52% whereas the H plane beam titling is ± 1 ° over most of the frequency range. The proposed novel antenna provides very high efficiency and it alleviates beam titling very effectively. This list is being further updated on a regular basis.The paper presents a dualband and compact antipodal Vivaldi antenna (AVA) array by using a dielectric lens (DL) and corrugations for 5G applications. A list of currently used antennasĪ detailed list of antennas has been mentioned below for your reference. Moreover certain applications would require several antenna and this may cause a confusion for novices. The next step is understanding the antenna type that would suit your application. You need to know the wavelength / frequency of the signal for the antenna, before beginning work on antenna design. Here we discuss basics of antenna design.Īntenna design begins by understanding your transmission requirements.
