We proposed a compact size planar dual band delt-apatch antenna in two layers of stacked PCB structure. The antenna supports two distinct operating modes at two different frequencies that a first mode of the antenna supports communication between multiple wearable devices on body and a second mode supports communication between wearable device to out body wireless network. The antenna design has been...
We proposed a planar delta-patch antenna that has a finite size ground plane and a truncated shorted corner to form its shape looks like a planar horn antenna to produce a surface mode radiation pattern in the end-fire directions. The antenna is designed and fabricated at 900 MHz band. The surface mode end-fire radiation of the antenna has been confirmed by experiment data. It shows that the antenna...
We proposed a grounded-stub coupling technique to enhance operating band of a planar monopole antenna. An effectiveness of the proposal is verified with a prototype design of a compact size printed monopole that has been fabricated and measured to demonstrate a broadband behavior of the antenna in a frequency band that ranges from 2.3GHz to 6.5GHz. A return loss characteristic of the prototype antenna...
A reconfigurable printed antenna is proposed that combines a tunable monopole and an adjustable loop antenna. The loop section controls a tuning operation for an upper frequency band while the monopole part contributes to a tuning for a lower frequency band of the antenna. It has been analyzed through simulations and measurements that the proposed antenna can operate for a tuning range as wide as...
