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...
In this paper, an iterative bandwidth mismatch compensation (BMC) algorithm is proposed to alleviate the need of multiple pre-trained models for recognizing different bandwidth speech. The BMC uses the concept of the bandwidth extension as similar as in the speech enhancement approaches. However, it aims at directly improving the recognition accuracy instead of speech intelligence or quality an...
A flexible circularly polarized (CP) wearable antenna is proposed for a wireless body area network at the 5.8-GHz industrial, scientific, and medical band. The made of polyimide foam material. CP radiation enabled by loading two pairs shorting pins on rectangular patch antenna. 3-dB axial ratio (AR) bandwidth doubled adding inverted L-shaped parasitic stubs both sides For validation, with dimen...
A substrate-integrated waveguide (SIW) antenna is an implementation of a in microstrip antenna. The antenna, as low-profile suffers from narrow impedance bandwidth. This paper proposes novel bandwidth enhancement method for solving Bandwidth was achieved by using quad-resonant frequencies. frequencies are resulted the hybrid half-mode (HMSIW) cavities between inner and outer cavities. HMSIW cav...
