Design of a Novel Wideband and Dual-Polarized MagnetoElectric Dipole Antenna

In this article, a high‐gain and dual‐polarized antenna with UWB operation is proposed. The antenna is composed of two tapered dipoles as radiating elements, which are arranged orthogonally and fed perpendicularly to achieve polarization diversity. A metallic cavity reflector is placed behind the radiator for high gain radiation entire the operating bandwidth. To validate the design method, an antenna prototype is designed, fabricated, and measured. The measured results demonstrate that the proposed design has good performance with |S11| ≤ −10 dB and isolation ≥20 dB over a frequency band 3.2‐8.8 GHz, equivalently to about 93.3%. In addition, unidirectional radiation pattern and broadside gain of from 8.1 to 11.8 dBi are obtained across the operating bandwidth.

Ultrawideband high‐gain dual‐polarized antenna with anti‐interference capability

Tran

2019

In this article, a high‐gain dual‐polarized antenna with band‐rejection capability for ultrawideband (UWB) applications is proposed. Tapered dipoles are chosen as a primary radiator to achieve UWB operation and it is reflected by a metallic cavity reflector for high gain radiation. A notch at WLAN band is realized by etching a set of four bent slots in the radiating elements. The measured results demonstrate that the proposed design with overall dimensions of 0.69λ L × 0.69λ L × 0.16λ L (λ L is free‐space wavelength at the lowest operating frequency) has operating bandwidth of 95.1% (3.2‐9.0 GHz) and the rejected frequency band from 5.0 to 5.9 GHz. Additionally, good unidirectional radiation patterns with a broadside gain from 8.1 to 11.5 dBi and radiation efficiency of better than 90% are also achieved.

“…Patch antennas have been widely used in wireless communication by the reason of their low profile, low cost, and easily integrated . However, these traditional patch antennas normally exhibit a narrow bandwidth due to their intrinsic property of single‐resonance radiation.…”

This article presents the design of a differential‐fed dual‐band antenna for wireless sensor network applications. A novel method is applied to enhance the bandwidth of a differential‐fed square patch antenna by loading shorting pin. Initially, a differential‐fed square patch antenna is introduced to generate the odd‐modes, that is, TM10, TM12 and TM30. Subsequently, with the adoption of a shorting pin, TM30 mode can be adjusted in proximity to TM12 mode for a dual resonance. At the same time, there is no effect on TM10 mode. A prototype antenna is fabricated and experimentally measured to verify the proposed method. Measured results show that the impedance bandwidth of the proposed antenna at the higher frequency band can cover from 5.11 GHz to 5.69 GHz while the lower frequency band operates from 3.35 GHz to 3.43 GHz.
