A new annular slot antenna (ASA) is proposed in this paper. The slot is perturbed to match the impedance of the fundamental and first-order modes of the annular slot. Results simulated using Ansoft HFSS are presented, which show that this new antenna can provide a dualband operation. The proposed ASA can be applied to IEEE802.11 WLAN systems.
A dielectric resonator antenna (DRA) is placed on top of an L-probe-fed slotted cavity to form a circularly polarized (CP) hybrid antenna. The zonal slot is perturbed to excite CP fields in the lower band, whereas the DRA located on top of the cavity is fed by an inclined slot to excite CP fields in the upper band. Ansoft HFSS was used to simulate the proposed configuration. The return loss, axial...
A dielectric resonator antenna (DRA) is placed on top of a slotted cavity to form a hybrid antenna. An L-probe is placed inside the cavity to feed the zonal slot, cut onto the cavity, and the DRA simultaneously. Ansoft HFSS was used to analyze the proposed hybrid antenna, which provides a dual-band operation. The proposed antenna can be applied to IEEE802.11 WLAN systems.
