Bandwidth Enhancement of Circularly Polarized Square Slot Antenna
Bandwidth enhancement technique of circularly polarized square slot antenna is presented in this paper. A square slot antenna with the components of L-probe separated could achieve an axial ratio (AR) bandwidth of 33.84%. Placing Stubs in the slot by studying the electric field behaviour could enhance the AR bandwidth by around 10%. Creating an L-shaped slot on the ground plane, where the elect...
متن کاملCircularly Polarized Square Ring Slot Antenna with Arrow-Shaped Structure
© 2009 ETRI Journal, Volume 31, Number 5, October 2009 A novel design of a compact square-ring slot microstrip antenna for achieving circular polarization (CP) operation is proposed and experimentally studied. By using an arrow-shaped slot structure as a radiating element, the resonant frequency of the proposed antenna is significantly lowered, which can lead to a large size reduction for fixed...
متن کاملNovel Compact Circularly Polarized Square Microstrip Antenna
A novel compact circular-polarization (CP) operation of the square microstrip antenna with four slits and a pair of truncated corners is proposed and investigated. Experimental results show that the proposed compact CP design can have an antenna-size reduction of about 36% as compared to the conventional corner-truncated square microstrip antenna at a given operating frequency. Also, the requir...
متن کاملOptimized Circularly Polarized Bandwidth for Microstrip Antenna
In very high frequency performances such as spacecraft, satellite & missile applications where the size, weight, cost, performance, ease of installation & aerodynamic profile are constraints microstrip antennas (MA) are used to meet these requirements. In spite of limitations such as small bandwidth, low gain and low power handling capability, microstrip antenna offers good performance over oth...
متن کاملDesign of Slot Cut Circularly Polarized Rectangular Microstrip Antenna
Circularly polarized slot cut rectangular microstrip antenna on thinner substrate is proposed. The dimensions of the slots are modified such that the resonance frequencies of the two orthogonal modes are close to each other to realize circular polarization. To improve upon the gain, three layer suspended configuration is proposed which yields VSWR and axial ratio BW of 40 and 9 MHz, respectivel...
