High gain cylindrical dielectric resonator integrated with horn for multiband wireless applications

Abstract

In this article, a multiband high gain cylindrical dielectric resonator (CDR) integrated with conical horn antenna is reported. This antenna has been designed for multiband wireless frequency applications. To enhance the gain, modified conical‐shaped horn is integrated to the CDR. The proposed antenna resonates at 2.3, 3.5, 3.9, 7.5, 9.2, and 9.95 GHz, respectively. Antenna attains measured 14.1 dBi peak gain at 10.7 GHz resonant frequency. In all the frequency bands, antenna offers more than 80% radiation efficiency. Simulated and experimental results show a commendable agreement. This antenna covers LTE services, Citizens Broadband Radio Service, WiMAX, vehicular communication, cellular communication, and radar applications.

High power balanced TEM horn antenna for ultra wide band radiator

“…Designs reported in 21 and 36 are having pbw higher than designed TEM horn, but power handling capacity of the antennas is not discussed. Dielectric resonator antenna (DRA) discussed by Chauhan et al 37 is a multiband resonant antenna which covers different frequency bands 2.2–4.6, 7.3–7.7, and 8.6–10.9 GHz, tend to be dispersive in nature. Proposed TEM horn antenna in our case is an ultra wideband antenna, which covers a frequency band of 0.135–1.5 GHz and is nondispersive in nature.…”

A differential‐fed dual‐polarized antenna with gain enhancement using hollow dielectric patch resonator

“…To meet the development requirement of high gain, the gain enhancement approaches of the DR antenna have been widely studied, 8‐16 which generally fall into three categories. Among them, the most common approach is to integrate the DR with a horn 8‐10 . Another approach uses the multilayer stacked anisotropic resonator to increase the radiation from the sidewalls of the DR 11‐13 .…”

“…[3][4][5][6][7] Nevertheless, the conventional DR antenna with uniform medium radiates through both the top wall and sidewalls, which has relatively low gain compared to the MP antenna. 3 To meet the development requirement of high gain, the gain enhancement approaches of the DR antenna have been widely studied, [8][9][10][11][12][13][14][15][16] which generally fall into three categories. Among them, the most common approach is to integrate the DR with a horn.…”

“…Among them, the most common approach is to integrate the DR with a horn. [8][9][10] Another approach uses the multilayer stacked anisotropic resonator to increase the radiation from the sidewalls of the DR. [11][12][13] Furthermore, benefiting from multimode nature, designing the DR antenna to operate at the higher-order modes is a convenient and effective way to enhance the gain. [14][15][16] However, the majority of the resultant antennas are complicated in structure or high in profile, which will be a major obstacle to the DR antenna in certain spacelimited applications.…”

Asymmetric liquid flow control polarization reconfigurable cylindrical dielectric resonator antenna for wireless communications

“…DRAs are characterized by high radiation efficiency, low metallic losses, compact size, and ease of excitation method. It provides broad bandwidth (BW), low quality factor ( Q ‐factor), and high gain compared to traditional microstrip antennas 3,4 .
