Stacked Patch Antenna

A Double Frequency stacked patch antenna array, DESIGNED for the frequencies of 1.348 GHz and 1.575 GHz in L-Band . The array accommodates sixteen antenna elements of 4×4 array fed by individualistic coaxial cable. The Radiation patterns for the two single element and array are studied. Comparison between the radiation patterns of a specific element and array are studied. Dual patch is used for both single element and antenna array, two patches resonates for two different designed frequencies of L-Band the impedance characteristics of both single element and array are studied and gains of single element and array are compared. ANSYS HFSS software is used for the simulation in this proposed work.

Stacked Patch Antenna

This article presents a thorough explanation on stacked patch antenna (SPA) for dual frequency applications. The strip antenna operates in L-Band at 1.34GHz and 1.579 GHz. The SPA designed and simulated on a Rogers RT Duroid 5880 substrate using dielectric constant of 2.2 and depth of 3.77mm for each layer. In Finite Element Method the proposed design is based Ansys electromagnetic suit (HFSS version 19.1.0), the proposed antenna simulated results provides good performance for dual band frequency applications in term of return loss and radiation pattern for dual frequency applications.

This paper proposes a microstrip patch antenna (MSPA) in the Ku band for satellite applications. The antenna is small in size with dimensions of about 40 mm×48 mm×1.59 mm and is fed with a coaxial cable of 50 Ω impedance. The proposed antenna has a wide bandwidth of 3.03 GHz ranging from 12.8 GHz to 15.8 GHz. To realize the characteristics of wideband the techniques of defective ground structure (DGS) and etching slots on the radiating element are adopted. The antenna is modeled on the FR4 substrate. A basic circular patch is selected for the design of a dual-frequency operation and in the next step DGS is introduced into the basic antenna and enhanced bandwidth is achieved at both the frequencies. To attain wider bandwidth two slots are etched on the radiating element of which one is a square ring slot and the second one is a circular ring slot. The novelty of the proposed antenna is a miniaturized design and unique response within the Ku band region which is applicable for wireless UWB applications with VSWR <2 and an average gain of 3.6 dB.
