摘要

本文提出了一种双频单极谐振器天线。天线工作在两个不同的频段，中心频率为2.4 GHz和5 GHz。为了覆盖WLAN的两个频段(即2.4 GHz的下频段和5ghz的上频段)，使用两个单极子:一个工作在较低的频段，另一个工作在较高的频段。然而，大多数这些天线在获得宽带特性方面存在限制，特别是在5 GHz频段用于WLAN应用时，同时工作在2.4 GHz。该天线在较高的频率上获得了良好的带宽，并通过MIMO配置提高了数据速率。仿真结果表明，单天线在2.4 GHz频段回波损耗为- 22.14 dB，在5.0 GHz频段回波损耗为- 35.43 dB。

Dual Band Monopole Antenna For WLAN MIMO Applications at 2.4 and 5 GHz

A dual band monopole resonator antenna is proposed in this paper. The antenna works at two different bands with central frequencies of 2.4 GHz and 5 GHz. To cover the two bands of WLAN (i.e., lower band of 2.4 GHz and upper bands of 5 GHz), two monopoles are used: one working for the lower band and the other working for the higher band. However, there is a limit in most of these antennas to obtain the wideband characteristic especially at the 5-GHz band for WLAN applications, when operating simultaneously at 2.4 GHz. The proposed antenna achieves a good bandwidth at the upper frequency, the data rate has been increased with the help of MIMO configuration. The simulated results are giving a very good return loss of −22.14 dB for 2.4 GHz band and −35.43 dB for 5.0 GHz for the single antenna.
