## Measured input impedance and mutual coupling of cylindrical-rectangular microstrip antennas opemrerl in h e TMol mode are presented and discussed. Results for the antennas on curued surfaces of dqferent cylinder radii are giuen, and the cun~ature effects on the input impedance and mutual couplin
## Abstract Closedβform expressions for the input impedance of halfβwavelength rectangular microstrip antennas fed by a coaxial line at any point on any one of the nonradiating edges and openβcircuited at the ends are derived. Good agreement between computed and measured data is obtained. Β© 2002 Wi
