| Description |
In this work, authors have investigated feed-probe influence on radiation characteristics of 90° circular
sector microstrip antenna (CSMA). It is observed that by
exciting a 90° CSMA with a feed-probe at two different feed-probe positions, two different modes TM01 and TM21 can be excited within the antenna structure. The resonant frequencies of these two modes are different but both of these modes have broadside radiation patterns in E and H plane. It is also observed that a 90° CSMA resonating at higher order TMo1 mode has nearly equivalent radiation characteristics with a circular microstrip antenna resonating at dominant TM11 mode resonating at nearly same frequency. Therefore, the 90° CSMA becomes a suitable alternative to a circular microstrip antenna.
