Abstract: In this article, low-profile and compact cylindrical dielectric resonator antenna along with circular slots and filtering structure for wireless application is reported. Proposed antenna is excited by annular-shaped microstrip line. Two ring-shaped resonators placed on opposite sides of feed line are working as a band-pass filter. These resonators are unified with wideband cylindrical dielectric resonator antenna and make it suitable for triple band operations with better isolation level. Dual ring-shaped parasitic slots on a partial ground plane are used to make CDRA more compact. The proposed triple band antenna has been analyzed, studied and optimized using Ansoft HFSS simulation software. Prototype of proposed geometry has been fabricated and tested. There is a better accord between simulated and measured results. The proposed design engenders three frequency bands i.e. 2.35–2.55 GHz; 3.35–3.65 GHz; and 5.1–5.42 GHz with a resonant frequency of 2.45, 3.55, and 5.35 GHz, respectively. Proposed antenna design may find suitable applications for WLAN (2.4/5.2 GHz) and WiMAX (3.5 GHz) bands. The proposed design shows an average measured gain of 4.71 dB in the three desired bands.
