Reconfigurable Metamaterial Structure at Millimeter Wave Frequency Range

Received Jul 18, 2017 Revised Oct 20, 2017 Accepted Nov 14, 2017 In this paper, reconfigurable metamaterial structure at millimeter wave frequency range was designed and simulated for a future fifth generation (5G) mobile-phone beam switching applications. The new proposed structure was composed of a bridge-shaped resonator (BSR) in the front face and strip line at the back face of the unit cel...

Reconfigurable Antenna : Narrowband Frequency Reconfigurable Antenna

Reconfigurable antennas have attracted a lot of attention especially in future wireless communication systems. Superior features such as reconfigurable capability, low cost, multi-purpose functions and size miniaturization have given reconfigurable antennas advantage to be integrated into a wireless systems. In this chapter, two types of reconfigurable antennas are discussed. First, frequency r...

Wide Range Voltage to Frequency Converter using PSoC3 Microcontroller

This design describes a wide range voltage to frequency converter in a single PSoC chip, which can measure wide range of voltage between 50mV-5000mV and found suitability in sensor applications. This design is implemented in a PSoC3 device IC CY8C3866. The design implements analog and digital user modules: an IDAC, COMPARATOR, PWM, COUNTER, UART and LCD. The comparator gets the analog input fro...

Improved Single Frequency Estimation with Wide Acquisition Range

An improved method for estimating the frequency of a single complex sinusoid in complex additive white Gaussian noise is proposed. The method uses a modified version of the weighted linear predictor to achieve optimal accuracy at low/moderate SNR while retaining its speed and wide acquisition range. Consequently, it has an advantage over known methods that use the weighted phase averager since ...
