Abstract- This paper presents a wideband patch antenna array in E-band for wideband operation. The proposed patch arrays are designed by using disparate resonance arms fed by microstrip. This proposed antenna covers the frequency ranges (S11<=-10 dB) from 40 to 80 GHz. The main purpose of designing the proposed antenna to enhance the impedance bandwidth. By varying the length of the disparate arms, To broadening the impedance bandwidth. Microstrip feed is introduced for improving its impedance bandwidth and radiation performance. The proposed antenna arrays have some features suchas resonance tuning ability, low-fabrication cost and enhanced bandwidth. This antenna is simulated using HFSS and fabricated, tested for S-parameters and the performances is used forwideband applications. The proposed antenna mainly used for satellite communication.

AMAJOR hurdle in the micro strip patch antenna array design is its limited band width. The substrate-integrated waveguide (SIW) technology is used to design a cavity- backed micro strip patch antenna array at low cost multilayer printed circuit board process and Co-axial feed line is used in this antenna . However, at low frequencies where the radiation performance tends to poor due to strong mutual coupling between separated elements, The patch array covers offer as a lower profile and light weight matching structure. Asymmetric coplanar waveguide(ACPW) series feed network is used to design a 2Ã—2 rotated patch antenna array . The implementation of 2Ã—2 patch array Using polystrata process . The large array are the main issue limiting its efficiency and application e.g., T/R modules and phase shifter . They enhance the isolation in micro strip patch antenna array.

ANTENNA DESIGN AND PERFORMANCE
The geometry of the proposed 1Ã—2 patch array is used. This antenna is composed of two radiating patches with three disparate resonance arms resonance which made up of FR4 substrate with
the dimensions of 15Ã—10mm^2. Patches are fed by the microstrip, which excite by slot line transitions with the T-shape slots on the opposite side of the substrate. The thickness and relative permittivity of FR4 substrate are chosen to be h=1.6 mm and 2.2respecyively connect to the ground plane with slot line sections. Both total width and length patches are 24mm.

SIMULATION AND EXPERIMENTAL RESULTS
The simulation results are made sing the Ansoft HFSS with the finite element method. Fig.1, displays the proposed 1Ã—2 patch array is designed. It mainly fabricated to cover the measured frequency range from 40 to 80 GHz for S11<=- 10 db. It includes the wide bandwidth in E-band. Fig.1, domonstrates that the proposed patch array operates at 40 to 80 GHz for measured -10-Db impedance bandwidth. The proposed design indicates better performance compared to other wide band patch arrays. The measured and simulated radiation patterns in the xz-plane(H-plane) and yz-plane(E- plane) at 9.5 and 9.8GHz for the proposed array shown in Fig.1, The gain of the 1Ã—2 and 1Ã—4 patch arrays with in the operational bandwidth is 7 and 8 dB, respectively. The 1Ã—2 and 1Ã—4 patch array are shown in Fig.9

In this paper, an attempt has been made to enhance significantly. The bandwidth of the suggested 1Ã—2 and 1Ã—4 patch array by introducing the pattern with disparate arms and microstrip-to-slot line feeding technique. The 1Ã—2 and 1Ã—4 patch arrays include 40 to 80GHz for wideband operation in E-band. The wide band operation shows that it can predict and explain the broad band properties of the proposed antenna.
