In this paper, there is a t shaped antenna patch on a 12mm X 12mm plane, with another patch which is inverted T shaped patch on the same plane. Its operated in the frequency range of 24GHz to 40GHz. It is a millimeter wave frequency antenna for 5th generation applications. Owing to its compact size it has less complexity, and fed by waveguide on both sides of patch[1]. It gives a bandwidth of 2GHz and 5.6 GHz in the range 24-26 GHz and 30-35GHz respectively. Radiation efficiency is of 83% at 40 GHz and directivity of 5.27 . We get to see two resonating frequencies, one at 28GHz and other at 37 GHz thus creating dual band antenna[2].

Dual Band Antenna

AbstractIn recent years, millimeter wave (MMW) has received tremendous interest among researchers, which offers systems with high data rate communication, portability, and finer resolution. The design of the antenna at MMWs is challenging as it suffers from fabrication and measurement complexities due to associated smaller dimensions. Current state-of-the-art MMW dual-band antenna techniques demand high precision fabrication, which increases the overall cost of the system. Henceforth, the design of an MMW antenna with fabrication and measurement simplicity is quite challenging. In this paper, a simple coplanar waveguide (CPW) fed single-band MMW antenna operating at 94 GHz (W band) and a dual-band MMW antenna operating concurrently at 60 GHz (V band) and 86 GHz (E band) have been designed, fabricated, and measured. A 50 Ω CPW-to-microstrip transition has also been designed to facilitate probe measurement compatibility and to provide proper feeding to the antenna. The fabricated single frequency 94 GHz antenna shows a fractional bandwidth of 11.2% andE-plane (H-plane) gain 6.17 dBi (6.2 dBi). Furthermore, the designed MMW dual-band antenna shows fractional bandwidth: 2/6.4%, andE-plane (H-plane) gain: 7.29 dBi (7.36 dBi)/8.73 dBi (8.68 dBi) at 60/86 GHz, respectively. The proposed antenna provides a simple and cost-effective solution for different MMW applications.

AbstractIn this paper, a compact, low-profile, coplanar waveguide-fed metamaterial inspired dual-band microstrip antenna is presented for Wireless Local Area Network (WLAN) application. To achieve the goal a triangular split ring resonator is used along with an open-ended stub. The proposed antenna has a compact size of 20 × 24 mm2 fabricated on an FR-4 epoxy substrate with dielectric constant (εr) 4.4. The antenna provides two distinct bands I from 2.40 to 2.48 GHz and II from 4.7 to 6.04 GHz with reflection coefficient better than −10 dB, covering the entire WLAN (2.4/5.2/5.8 GHz) band spectrum. The performance of the proposed metamaterial inspired antenna is also studied in terms of the radiation pattern, efficiency, and the realized gain. A comparative study is also presented to show the performance of the proposed metamaterial inspired antenna with respect to other conventional antenna structures in terms of overall size, bandwidth, gain, and reflection coefficient. Finally, the antenna is fabricated and tested. The simulated results show good agreement with the measured results.
