In this paper, the authors present a detailed explanation on performance of feed on a microstrip circular patch antenna for dual frequency applications. The antenna operates at Ka-band at 34.88GHz and 37.55GHz with an operational band width of 6.51GHz (32.79GHz to 39.30GHz). The antenna has been designed and simulated on an FR4 substrate with dielectric constant of 4.4 and thickness of 0.21mm. The design is analyzed by finite element method based HFSS simulator software (version 14.0), the simulated results shown that the proposed antenna provides good performance in term of return loss and radiation pattern for dual frequency applications.
