Abstract

This paper presents the design, simulated and tested results of a compact varactor diode integrated conventional pentagonal patch antenna with different sides and also compares the results with a similar patch antenna. Proposed pentagonal microstrip patch antenna (PMSA) was designed and simulated using HFSS.V.13 and ADS and its various parameters such as return loss, VSWR and input impedance were determined, and shape of this PMSA was modified by cutting various slots in it at appropriate positions. The variable capacitance diode loading method enables the impedance matching for the frequency band from 2.69 to 2.74 GHz for the value of VSWR between 1.05-1.11. The proposed antenna also gives circular polarisation radiation with slots. It is observed that the proposed antenna shows frequency agility behaviour in the frequency range 2.69-2.74 GHz with bias voltage varying from 0-5V..
