A Dual-Broadband Printed Dipole Antenna for 2G/3G/4G Base Station Applications

Abstract

A new dual-broadband printed dipole antenna for base station applications is proposed in this communication. This antenna has three different dipoles with the same feed point and an extra parasitic strip. The two arms of the three dipoles are printed on opposite sides of the substrate and symmetrical on the centerline, but the parasitic strip at the end of the dipole is just put on one side. Besides, a U-shaped reflector is designed at the bottom of the antenna to realize good radiation characteristics in the working frequency. The simulated and measured results show good agreement. The two studied bands are both broadened which, respectively, achieve 36.7% (690–1000MHz) and 47.3% (1710–2770MHz) for the lower and higher bands so as to satisfy the 2G/3G/4G wireless communication, and the corresponding gains of 4-5dBi and 5-6dBi are also obtained.

A Four-Layer Odd Function Symmetrical Dual-Polarization Equilateral Right Triangle Slot Printed Broadband Directional Antenna for Wireless Lab Measurement Applications

“…Table 4 and directional radiation. For mobile base station or lab measurement applications, the antenna in [9] does not support dual-polarization, even if [10][11][12][13]15] have better antenna gain in the frequency range of 1-6 GHz, but these antennas have insufficient bandwidth to cover modern wireless technologies and require extra feeding network design and expensive materials. Different from [10][11][12][13]15], the proposed antenna utilizes an odd function symmetrical equilateral right triangle slot to realize an ultrawide bandwidth of 1.37-7.12 GHz (135.5%).…”

“…In these literatures, the antennae have the features of directional, broadband, and dual-polarization which are presented. But, the operating bandwidth is not enough to cover the wider bandwidth, and the applications scenario is just limited for mobile base station [9][10][11][12][13]. To summarize all of the reference papers as above, we propose a new design for high gain, high isolation, and broadband directional antenna, which is comprised of the equilateral right triangle slot with odd function symmetrical pair of stubs; there are four stacked layers composed of two antennae and two reflectors are shown.…”

Design of circular-shaped microstrip patch antenna for 5G applications

“…Communications, whether wired or wireless, have been enabled among devices with polymorphous in the abilities and the dimensions, beginning from the central computer devices and laptops to the electronic devices used in the buildings, sensing components and mobile phones [2]. 5G network uses a variety of spectrum resources in millimeter waves, which is anticipated to considerably improve the communication capacity.…”

A Novel “回” Pane Structure Multiband Microstrip Antenna for 2G/3G/4G/5G/WLAN/Navigation Applications

“…With wireless applications becoming increasingly more popular, the requirements for antenna miniaturisation, multiple frequency bands, and ease of loading have grown considerably. In order to achieve multiple frequency bands, antennas are commonly designed with multiple feed points, and a U-shaped reflector is included at the bottom to expand the frequency band [1]. Antennas can also be designed for multiple iterations to improve their performance.…”
