This paper describes the design procedure of a deployable antenna for Cubesat applications operating in the UHF frequency band of 437 MHz. Due to the expected large size for operation in this band, the meanderline and Vivaldi miniaturization and broadbanding techniques are used to obtain a wider impedance bandwidth. This is to ensure the size compatibility of the proposed antenna to the compact Cubesat...
A recently developed compact planar Quasi-Landstorfer antenna is presented here. For this design, the reflector element was removed from the original Landstorfer antenna and the ground plane was modified to have the same behavior as the removed reflector element. By using the ground plane as a reflector, the overall size of the planar Landstorfer antenna was reduced by 44%. The smaller prototype Quasi-Landstorfer...
This work investigates the design of a flexible Minkowski fractal antenna. Two potential materials are included for examination - conductive copper tape and ShieldIt conductive textile. Both are designed and simulated to achieve a satisfactory resonance at the Very High Frequency (VHF) band for Land Mobile Radio (LMR) application through proper structure segmentation and iteration. Optimization concludes...
This paper describes the circuit design and measurement of a single stage RF amplifier for 5.8 GHz-band with IEEE 802.11a standards for WLAN applications. The circuit was simulated using Ansoft Designer where a 14 dB of gain; input and output return loss less than -10 dB were observed. The GaAs hetrojunction FET (HFET), capacitors and resistors are combined with the microstrip line pattern by silver...
