Antennas for Software Defined Radios
Jawad Y. Siddiqui, Senior Member, IEEE; Ajay Poddar, Fellow, IEEE; Ulrich L. Rohde, Life Fellow, IEEE
Abstract
There are several emerging technologies in the field of
antennas and propagation that are shaping the future of
wireless communication systems. Some notable examples
are advanced new antennas for software-defined radios
(SDRs). These advancements in antennas for SDRs have
the potential to revolutionize wireless communication.
This article explores some of the key future directions for
antenna technology for the new generation of SDRs that
will drive the next wave of connectivity revolution and their
indispensable role in humanitarian efforts, ranging from
disaster response to bridging the digital divide.

I. INTRODUCTION
In today's interconnected world, communication plays a
pivotal role in responding to humanitarian crises and driving
positive change in underserved communities. Antenna
technology is the backbone of modern communication
systems and has witnessed remarkable advancements
over the years. Antennas serve as the foundation of
wireless communication systems, enabling the transmission

and reception of signals over various frequencies. They
are essential components of satellite systems, mobile
networks, and radio technologies, facilitating data exchange
across vast distances. In humanitarian contexts, where
traditional infrastructure may be lacking or compromised,
antennas become invaluable assets in establishing reliable
communication channels. During natural disasters or
humanitarian emergencies, conventional communication
infrastructure often suffers severe damage, leaving
affected communities cut off from external aid and
assistance. In these critical situations, portable and resilient
wireless solutions come to the forefront. Humanitarian
organizations deploy rapidly deployable antennas, satellite
communication systems, and mesh networks to reestablish
connectivity swiftly. These wireless systems enable
vital communication between responders, government
agencies, and affected individuals, allowing for coordinated
relief efforts and efficient allocation of resources.
Access to quality healthcare remains a challenge in
remote and underserved areas. Wireless systems
have revolutionized telemedicine, enabling healthcare
professionals to provide remote consultations,
