In this article, a dual‐band hybrid cylindrical dielectric resonator antenna (CDRA) is designed, analyzed, and experimentally validated. Miniaturization and dual‐band frequency behavior are achieved by loading circular copper strips on top of the CDRA. Hence, the antenna resonates at 4.4 and 6.1 GHz covering −10 dB bandwidths of 600 MHz and 500 MHz, respectively. The proposed CDRA is excited using a rectangular slot for HEMY11 and HEMX11 modes. The proposed antenna demonstrates good gain (4.9 dBi at 4.4 GHz and 5.6 dBi at 6.1 GHz), high efficiency (>88% for all operating bands), and good FTBR (>10.08 dB in both principal planes for both operating bands). Moreover, the higher frequency band can be independently controlled by adjusting the parasitic strips width (d) and gap (g).

“…7 In open literature, different dual-band circularly polarized dielectric resonator based antennas have been reported. [8][9][10][11][12][13][14] Fang et al proposed a dual band circularly polarized cylindrical dielectric resonator antenna (DRA) with the assistance of quadrature coupler. It provides Axial Ratio (AR) bandwidth of 12.4% and 7.4% in lower and upper frequency band respectively.…”

In this communication, a dielectric resonator based circularly polarized antenna is designed and investigated. A modified aperture is used to excite dual cylindrical dielectric resonator (CDR) blocks. Two important characteristics of the proposed radiator that makes it all the more attractive are as follows: (i) excitation of dual radiating modes that is, HEM11δ and TE01δ mode in cylindrical DR along with the support of dual‐band circularly polarized (CP) waves; (ii) arrangements of dual CDR blocks to reduce the Q‐factor which is useful to enhance the impedance bandwidth of both frequency bands. Fabrication as well as experimental measurement of the antenna prototype has been done for verifying simulation outcomes. This antenna design operates over dual frequency bands, that is, 5.01‐6.41 GHz and 7.3‐7.9 GHz with the fractional bandwidth of 24.73% and 9.39%, respectively. It supports CP waves over the frequency range 6.1‐6.5 GHz and 7.4‐7.8 GHz. The proposed antenna backs right‐hand circularly polarized (RHCP) radiation with an average gain of 4.5 dBi. These characteristics make it well fitted for WLAN, WiMAX (5.2/5.5/5.8 GHz), and downlink defense purpose satellite communication (7.2‐7.7 GHz).

In this paper, two Dielectric Resonator Antenna (DRA) models fed through a pair of diagonally coupled asymmetric L‐slots are incorporated on the ground plane of size 44 X 44 mm2 with a strip line feed underneath the substrate are presented. The proposed DRA‐1 is a triband antenna, resonates at 5.2GHz, 6.7GHz and 9.85GHz with a gain of 5.6dBi, 5.66dBi and 9.8dBi respectively. The bandwidth offered at Circularly Polarized (CP) band by DRA‐1 is 1.95 GHz (6‐7.95 GHz). The proposed second model DRA‐2 operates at 5 GHz, 6.4 GHz, 7.8 GHz and 10.3 GHz with a peak gain of 5.5dBi, 5dBi, 6.1dBi and 7.8dBi respectively. The quad‐band DRA‐2 offers two CP bands with bandwidths of 1.3GHz (7‐8.3 GHz) and 1.2 GHz (9.8‐11 GHz). The multiple operating bands of the proposed DRAs are appropriate for different wireless applications such as WLAN, C‐Band and X‐Band range of frequencies.
