Abstract
In this paper, we propose a dual-broadband multiple-input multiple-output (MIMO) indoor base station antenna for 2G/3G/LTE systems. The proposed MIMO antenna has a low profile with its overall dimensions of 220×220×42 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> and utilizes both spatial and polarization diversities. The antenna operates at 800-960 and 1700-2700 MHz simultaneously, with the return loss of higher than 14 dB across both frequency bands. The isolations of the antenna are 18 and 25 dB, with antenna gains of 3.6 and 7.2 dBi for the lower and upper frequency bands, respectively. The proposed MIMO antenna is designed and fabricated with its practical deployment in mind, such as the durability and overall low cost. Comparing with existing commercial 2G/3G/LTE antennas, our proposed design offers a more compact size and simpler feeding structure.
Highlights
The rapid development of mobile communication technology has placed higher and higher demand on the requirement of wireless communication devices for achieving faster data processing and lower bit error rate
By combining a monopole as a vertically polarized (VP) element and printed dipoles as horizontally polarized (HP) elements [1]–[5], a dual-polarized antenna can be realized for 2G/3G/long-term evolution (LTE) indoor base stations covering both frequency ranges of 800 - 960 and 1700 - 2700 MHz
In this paper, based on our previous design of a microstrip-type dual-wideband element [30], we propose a multiple-input multiple-output (MIMO) indoor base station antenna utilizing spatial and polarization diversities for 2G/3G/LTE systems operating at 800 - 960 MHz and 1700 - 2700 MHz simultaneously
Summary
The rapid development of mobile communication technology has placed higher and higher demand on the requirement of wireless communication devices for achieving faster data processing and lower bit error rate. In this paper, based on our previous design of a microstrip-type dual-wideband element [30], we propose a MIMO indoor base station antenna utilizing spatial and polarization diversities for 2G/3G/LTE systems operating at 800 - 960 MHz and 1700 - 2700 MHz simultaneously. Practical issues such as maintaining a low cost and durability of materials, input power rating, as well as meeting the passive intermodulation (PIM) requirement in industry have been taken into consideration in our design. It is worth mentioning that the MIMO antenna proposed in this paper has already been manufactured in a large quantity and is currently being used in several local mobile networks
