A Low-profile 4-element Circularly Polarized Hexagonal DRA Array for Triple-band Wireless Applications
Main Article Content
This paper presents a triple-band low-profile circularly polarized (CP) hexagonal dielectric resonator antenna (HDRA) array for various wireless applications. A 4-element linear array is designed using a simple microstrip power divider to improve the performance of the HDRA. This HDRA excites TEd01 mode at a first resonant frequency of 1.52 GHz. The proposed design operates in three frequency bands, i.e. 1.44 - 1.61 GHz, 2.95 - 3.27 GHz, and 4.00 - 4.84 GHz with the fractional bandwidth of 10.98%,
11.02% and 22.20%, respectively. It also provides good gain and more than 70% of radiation efficiency with a better radiation pattern at all the resonating points. Further, it has a CP bandwidth of 50 MHz and 650 MHz around 3.12 GHz and 4.25 GHz, respectively. The proposed HDRA array is suitable for different wireless applications such as GPS (1 - 2 GHz), WiMAX (2 - 4 GHz), and WLAN (4 - 8 GHz).
