“…This has been done to bring together different services into a single compact unit handset, while keeping high‐performance standards. To accomplish that it is necessary to develop small antennas that are able to operate in several frequencies [1–9]. Dielectric resonator antennas (DRAs) are integrated structures with predefined formats and are able to radiate if the dielectric constant is high (ε r > 10) [2].…”

A rectangular dielectric resonator antenna (DRA) based on CaTiO3 with low profile, dual‐band and high dielectric constant is proposed as a candidate for application in wireless communication systems at the microwave band. The proposed geometry is composed by a dielectric resonator mounted on a microstrip line section that is used as the feeding element. The antenna analysis is performed using Ansoft HFSS that implements the finite element method. Measured results are shown for several DRA prototypes. A good agreement between numerical and experimental results is observed. © 2012 Wiley Periodicals, Inc.

fabricated on three-layer printed circuit board substrate with dielectric constant of 3.5 and thickness of 0.76 mm (Fig. 4)]. The 2 Â 2 rectangular patch array and the feed network for circular polarization are implemented on the top layer and the bottom layer, respectively. The middle layer is used as a ground plane. Figure 5 shows the measured isolation between transmit and receive ports. The isolation of about 54 dB is obtained at 5.53 GHz, which means that the isolation is enhanced compared to the normal circulator. Figures 6 and 7 show the measured radiation pattern of transmit and receive array antenna at 5.5 GHz. The gain of the array antenna is about 6 dBic and the axial ratio is less than 2 dB. CONCLUSIONSThe design of the integrated microstrip patch array antenna with enhanced isolation has been presented and measured. The isolation of about 54 dB is obtained at 5.53 GHz and the gain of the array antenna is about 6 dBic and the axial ratio is less than 2 dB. The proposed structure can produce a full-duplex transceiver with transmit and receive operation at the same frequency and with the same polarization. It also shows the possibility of using larger arrays of this type in millimeter wave bands for shortrange communications or radar systems.ABSTRACT: A rectangular dielectric resonator antenna (DRA) based on CaTiO 3 with low profile, dual-band and high dielectric constant is proposed as a candidate for application in wireless communication systems at the microwave band.
