“…In the past, wire bond or air bridge [6][7][8] structures were used to allow two signals to pass each other. Considering that these structures cause significant signal and power losses and slow transmission, planar structures [9][10][11][12][13][14]17] as a new perspective have become very important. Calculated and measured values between lines and ports at the operating frequencies of Radio Frequency (RF) elements are carefully evaluated in terms of system bandwidth and lossless transmission.…”

“…Calculated and measured values between lines and ports at the operating frequencies of Radio Frequency (RF) elements are carefully evaluated in terms of system bandwidth and lossless transmission. With the beginning of studies on structures to change the frequency range and increase the bandwidth of conventional MICs [9], there is a new interest in the design and analysis of both single and dual-band structures in these circuits and gates operating at different frequencies [7,[10][11][12][13][14][15]17].…”

Microwave integrated circuits (MICs) are becoming increasingly important in communication systems due to their ability to efficiently transfer power and signals using crossover structures. Conventional crossover designs, however, suffer from significant signal and power losses, limiting their performance. In various studies, there are complex planar designs, MICs and Radio Frequency (RF) circuits operating from frequencies and bands. This paper proposes a novel fully symmetric four-port microstrip planar crossover that overcomes these limitations. A square microstrip structure with a size of 80.0 × 80.0 ×1.6 mm³ is presented in the design, which has a planar crossover and wide band gap at an operating frequency of 2.1 GHz. The proposed design provides excellent isolation between ports and minimizes signal and power losses, making it a promising solution for MICs and RF circuits for LTE applications.
