This paper presents a dual-band dual-polarized antenna including one L-band vertically polarized antenna, four C-band horizontally polarized subarrays, and four C-band vertically polarized subarrays. Both the L-and C-band radiation elements are designed based on the concept of slotted coaxial waveguide antenna. The coaxial waveguide structure is in rectangular shape which is suitable for multi-element integration. And bending stripline inside the waveguide cavity plays the role of inner connector for the coaxial waveguide and exciter for radiating slots on the waveguide. Results show that impedance bandwidths of 14.9% for L-band and 5.9% for C-band are obtained with good port isolation. The antenna also exhibits good radiation performance with the low cross-polarization. The results indicate that the proposed antenna is suitable for synthetic aperture radar applications.

The finite‐difference time‐domain method (FDTD) is first applied to investigate the reflection and radiation properties of a finitely long coaxial antenna with circumferential slots on its outer surface. The end effect and multislot effect intractable for the moment method and mode‐matching method are analyzed efficiently and demonstrated in detail. According to the accurate analysis, the circumferential slots have a strong influence on the characteristics of the antenna. This effect can be used to effectively adjust the impedance matching and radiation pattern of the antenna. The verification of the method is also presented by reference to the experiment and the literature. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 21: 35–39, 1999.

An efficient modal‐expansion analysis is developed for obtaining the current distribution of a slotted coaxial line antenna with a length up to 10λ. In our analysis, the outer conducting body of a long and thin coaxial line is approximated into the thin prolate spheroidal, and the corresponding wave functions are used to express the electromagnetic fields outside the coaxial line. Matching the outer and inner electromagnetic fields over the slots on the surface of the coaxial line, the current distribution can be efficiently solved. Reasonable accuracy is obtained when results of this method are compared with those available in the literature. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 21: 372–377, 1999.
