Γ Shaped Slotted Compact Circular Crossover for Communication Applications at 2.45 GHz

Abstract

Modern communication system technologies, crossover structures are widely used as one of the main elements in microwave circuits in different operating environments. Nowadays, microwave circuit elements provide continuity and development in these areas by triggering rapid transformation in terms of communication, protection and security. Innovative and contemporary solutions are becoming an important issue with increasing product demands and production capacities. This paper introduces valuable solutions in this direction of crossover design for microwave integrated circuits. A circular cross with symmetrical internal transmission line covering the frequency with WLAN (wireless local area network), WiMAX and GSM applications is proposed. The circular crossover bandwidth -10dB is between the frequencies 2.32 GHz and 2.58 GHz. The designed microwave circular crossover size is 40mm x 40mm x 1.6mm. The efficient compact microwave crossover design method in planar circuits promise to improve the performance and versatility of microwave circuits. The efficiency in 2.45 GHz frequency transitions brings closer to realizing efficient band applications for wireless communication and paves the way for future developments in this field.
