Theoretical investigations of an annular elliptical ring microstrip antenna using Green's function technique
1999
IEE Proceedings - Microwaves Antennas and Propagation
Analytical expressions for the Green's function of an annular elliptical ring microstrip antenna (AERMA) are developed and reported. The modal, radiation and input impedance characteristics of the TM, modes are determined from these expressions. The resonant frequencies of odd modes are greater than that of the even modes for all TMnl modes (n = 1, 2, 3, ...) u d k e elliptical microstrip structures. The radiation pattern and input imedance curves of TMI2 mode on comparison with available
