“…Nowadays, the wireless data exchange has increased considerably due to the different methods for the occurrence and use of the data very high demands for high speed wireless communication have increased [1] [9]. A MPA has been broadly put in an application for contemporary wireless communication systems on account of its worthiness of nominal fabrication expenditure, nominal silhouette, and unchallenging assembling with circuits [3] [8]. For wireless communication, there is a need for efficient antenna transmitting and receiving data at the highest data transfer rates and lower transmission power [1].…”

This paper presents the design and simulation of a microstrip patch antenna (MPA) which is modeled by placing several rectangular copper layer with conductive characteristics on a substrate material with dielectric constant 3.0 and 22x18x1 mm 3 geometry. This microstrip path was designed with copper material which had a very thin thickness for patch and ground. In this study, a change in resonance frequency and return loss characteristics were observed for several substrate thickness values. The radiation characteristics of the single and dual band microstrip patch antennas (MPAs) are analysed in the frequency range of 5 -25 GHz. The microstrip patch antenna (MPA) radiate at a frequency of 15.32 GHz with -45 dB return loss. For the designed single and dual band MPA design, some electromagnetic properties such as return loss, surface current and radiation patterns were simulated. The characteristic of goods and chattels of the proposed antenna are analyzed by using the software CST Microwave Studio.

“…Branch line hybrid couplers are prominently used in the design of many microwave circuits (e.g., data modulators, phase shifters, balanced amplifiers and feeding networks). Most of the research on this structure focuses on achieving circuit miniaturization and bandwidth plus isolation enhancement through different techniques, including left-handed transmission lines [1], via-holes [2,3], air-gaps [4], stubs [5,6], coupled [7,8] and π-shaped lines [9].…”

A topology, equations and design methodology for complex impedance-transforming branch-line hybrid couplers are presented. This method also allows the realization of real impedancetransforming to higher impedances. Limitations for real, imaginary and complex impedances are discussed. Test results are shown for a 3 dB 50 to 450 Ω hybrid coupler, at a 2 GHz center frequency, with a 21% bandwidth, an amplitude balance of 4.35 ± 1 dB and a phase balance of 92.16 • ± 8.8 •. To showcase the complex impedance scenario, two 3 dB 50 Ω to 70 − 200j Ω are measured at a 2 GHz center frequency. One of these couplers uses a technique for reducing the chip size, yielding a 22.5% bandwidth, 4 ± 0.9 dB amplitude balance and 93.22 • ± 6.74 • phase balance, while accomplishing a 25% size reduction.
